@Rxe08 Yep, "engine turning" surface decor on pocket watches, firearms, calculators, steam engines. Look up Guilloche, and rose engine lathe, a Victorian analog computer spirograph. They came THIS CLOSE to discovering the Rainbow Holograph geometry and 3D imagery from mechanical "ruling engine" diffraction. Secret of master portraitist: fine nested curves on painting's eyes gives 3D glitters, so they almost follow you.
This is amazing! Can't even imagine how much work you have put into these images. But why do you call it "holograms"? It's a different concept, and, I guess, it would be way cooler to have your own word for that :)
@pshved I only could figure out how these things worked because I already understood Benton Rainbow holograms. Basically they both work the same! Rainbow holograms have curved lines which reflect two different highlights/glints into your two eyes. Main difference is that Rainbow holograms use microscopic nested hyperbolae, not big thick circles. (Imagine if you could use lasers and wave interference to create scratch-holograms?)
The late SAB@media, the inventor of Rainbow Holography, disagrees with you. I mean this literally, let me search out our brief email conversation from ~1996. (Of course, perhaps he later changed his opinion back again!)
All white light (rainbow) holograms are based on "flares which move by different circle tracks."
Gedankenexperiment: suppose we create a CG Benton holo. Suppose we randomly scramble the fringe spacing of each zoneplate, but otherwise preserve those nested hyperbolae. What happens? When illuminated, still it reconstructs a 3D virt image! But now the image is white, not rainbow. The 3D image now contains no wave interference phenomena, only geometrical optics. Only astimatic specular/scattering reflection.
A "ruling engine" can draw a diffraction grating, but it also can draw the zoneplates of a conventional holo.
If a ruling-engine creates the zoneplates of a Benton Rainbow Holo, you'll find that, even if the fringe spacing is made >> lambda, the hologram still reconstructs the 3D scene. This is expected, since Benton holograms are wavelength-independent. WHY does their image struct remain constant wrt changes in wavelength, or to fringe spacing? That's the real question.
Some say that holograms require sine fringes, not scratches. I see this as wrong, since diffraction gratings once were made by "ruling engines."
Some say that holograms must include wave interference. Valid issue. Off-axis holos are obviously holograms. But Benton rainbow holograms employ interference only to produce the fringe pattern, not to reconstruct the 3D virt. image. That's why they still work with broadband light.
So if I take a compass and scratch a curve in a piece of plastic with a dark back, I'll see a point that appears to be 3-d? What if I don't? Did I do something wrong?
who cares if it is not a true hollogram!!! can't you se when something is valuable just for the work, the efort, or the simple try??? Man this is genius!!! so simple so magic! great!!!! I hope you can create more and more sofisticated!!
Hit with a microwave beam? That loud hum starting at 0:36, that wasn't caused by software or editing. That hum was obvious during playback when I was still standing out on the sidewalk. There was no audible hum at the time. Also, it takes quite a strong EM field to overload a camera and inject sound (Tesla coils could do it.) Perhaps I was briefly "painted" with a kilowatt microwave beam? OK, I gotta go stuff tinfoil under my golf cap now. Or perhaps build a helmet from 3mm lead sheets.
@Escapist166 Princess Leia projected in space is not a "hologram," that's an SF movie effect and doesn't exist in the real world. No scientist has a clue for how to create a Star Wars "hologram." Those aren't invented yet.
Holograms are opaque metal plates or transparent plates with interference patterns. When illuminated, a 3D image floats within the plate (or floats in front.)
Dr. Dennis Gabor got the 1971 Nobel for his invention of holography, and he coined the term "hologram" I believe.
@wbeaty actually; research is being done, as they have discovered how to program photons to 'detonate' x seconds miliseconds after being shot. this means they can shoot a group of photons up from a source, making each detonate at a specific spot in the air, and thus creating an image. they have managed to create 'actual' holographic images of butterflies, etc (though, granted, not in very high resolutions yet, but still; it works).
you should look it up! props for these drawings, mate. really.
@Rocksolid88 Yeah, AIST's thing is the closest so far, but it's a multi-kilowatt pulse laser. Those points of light are the laser focus, where it shreds air molecules into ions, makes noise like tiny firecrackers. See bit.ly / 2KYjAe
If you stuck your hand in there, it would blow little holes in your flesh. Perhaps all the way up to your shoulder! :) R2-D2 should have aimed his Princess-Leia hologram at the Jawas!
@Escapist166 nope, princess Leia projected images aren't holograms. They're SF movie effects, and today's scientists have no clue about how to create such a thing in real life. Not invented yet.
Genuine holograms are a metal plate or transparent plate with microscopic interference patterns. When held under sunlight or laser light, a 3D image appears within the plate (or it can float in space outside the plate.) Dr. D. Gabor invented holography in 1940s, got the Nobel Prize for it in 1971
@wbeaty well,they have invented a hologram which you can see a image from all angles,for instance a person from all angles if you walk around.it dosent float in mid air through,its just a circluar screen attached to a cylinder
@colsupertaco Yep, "The Kiss" is the famous example. Those are multiplex holograms, white-light holograms basically the same as this one. In theory you could make a specialized scratch-hologram on a flexible sheet, then wrap the sheet into a cylinder shape. Put a light source above, and a glowing object would appear in the middle, and you could walk all around it. The secret is to make an animated hologram of a 3D rotating object. Then when you turn the cylinder, the object seems to turn
@wbeaty actually what you're talking about is a holograph... you bathe an object in laser light, you shoot an interference laser into it and film THAT... then shoot a laser through the film and you've got a fully 3d projection of that object.
Anyways, I think I'm just gonn go with the acrylic stuff too. I've been using cd cases to try the stuff out, but it doesn't give the 'tiny stars' like you get. Also could we use this type of stuff for schoolwork or is it copyrighted or something :p
And I don't mean a copy of what you have ofcourse, but something similar.
@ewak1991 no copyright, it's for public use. See the main website for the history. After playing with this for a couple of years, I decided not to patent it. Instead I published the secret as an internet meme, to see how far it would spread. Kids could use it to confuse and frighten their physics teachers, since "hand-drawn holograms" are like a weird alien technology which should be impossible. All that was in 1995. I only posted a video more recently.
Do you think I could also use a marker to make the back of the styrene plastic black, or does it have to be paint? Also, what kind of paint, or does any type do the job?
@ewak1991 styrene CD and DVD cases work great. The dark color is just for higher contrast. In this video half the holograms were done using clear acrylic backpainted black.
@ewak1991 Can you get the corner spots working? So the invisible 3D cube has glowing tips?
Check out the 2003 SPIE paper for instructions on making 3D straight lines. Basically you lay down a 3D spot between two existing 3D spots, then lay down more between those, in 3D always placing them in half way between two others. That fills in the straight line.
The outer lines are also working, so I can basically get those to disappear like they moved behind the middle vertical line, however there is no middle line so it doesn't look right.
I'm having the same problem as somebody else that commented a while ago. It's kind of hard to understand cuz this isn't my first language....
@ewak1991 FAQ #7 is for a 3D lines entirely inside the plastic surface, like cube at 0:32. For these, each straight line has a row of "fulcrum points," and another row of "top of the arc" points.
I made lots of holos within the surface before I dared tackle one where holo lines penetrate the surface. For these, the two rows of points will cross each other at the spot where the holographic line penetrates. (The radius goes to zero. For all points above surface the arcs are inverted:"U" shape
Oh, and a video projector makes a good spotlight indoors. Use msPaint etc. to set the projection to all white screen (or all blue, etc.), then blur the focus. For classroom demonstrations I can find an old overhead projector in the school: place it atop a tall filing-cabinet and aim the beam downward.
@MatsEP Type-1 errors: thinking fake things are real.
Type-2 errors: thinking real things are fake.
Go on Google Scholar. I have one research paper there (2003 SPIE IS&T Elecr. Imaging), but several others exist. Or just click my link. The technique was invented in 1980. Physicists at Kodak stumbled across it in 1992 and published the details. I discovered it myself in 1994 and posted it online for kids. Since then, hundreds (perhaps thousands) of people have used it for science fair.
What is the difference between incandescent and fluorescent light when it comes to using them as a light source for viewing these holograms? Which would perform better? I'm looking for an effective indoor light source.
@elverg47 use anything that works for conventional holograms. Spotlights should be lensed "pin spots" 200 watts or more. Try a video projector or slide proj as a light source (set it for a blank white rectangle image.) The main rule is, the greater the source width, the fuzzier the holo image. (Arc welder good, cloudy sky bad.) Streetlights at night work great. Frosted bulbs are poor unless distant and very high wattage. Fluorescent tubes in a white ceiling don't work at all.
What is the science behind this? Are hand drawn holograms truely "holograms" or is it just a name? This is a really interesting find, thanks for posting.
I'm trying to replicate your results. I have read your little tutorial though my holograms are nowhere near as clear as the ones in this video. What are some possible sources of error?
@elverg47 See main website, click the link above (just below "LIKE" button.) See "are these really holograms?" See "I tried and it didn't work!"
The secret is $15 pro compass, use a dull compass point (not a needle, more like a nail), also greasy plastic (a tiny dot of oil rubbed with paper towel,) also use soft plastic, CD jewel box, styrene or polycarb, not the harder plexiglas acrylic. Scratches must be smooth, polished, like silent grooves on a vinyl record. Any vibration ruins it
My dad worked in a holography at the university of Michigan lab as a grad student, and when I was young he showed me how to do something like this, but lord, our little home project never turned out that well. bloody amazing. did you etch those paths by hand? how did you get the termination of the arcs so precise on the object-hidden-by-opaque-planes?
@Thuringen Just make about a hundred of these. I started out in 1994!
You do need good architect's compass. But also a dull nail point works much better than needle-sharp compass point. And slightly greasy polycarb plastic helps greatly.
The endpoint positions just use a simple trick I invented. Another trick lets me quickly create straight 3D lines. By cheating, I can become a human computer! See the main website, it's hidden in the SPIE 2003 "invited paper."
I read about this method a long time ago, about fifteen years ago, and while I understood what was meant to happen, I could never get it to work properly. The method I saw called for dividers scoring lines on acetate.
This is the first time I've ever seen it work, so kudos!
@andarks Nope, but use a video projector as a light source. Feed it a white square. Or overhead projector, etc. At night, go out under a single streetlight.
i can easily see how you made that but to do it without making the design before making the hologram you need to have experience but if your a first timer think of the design first :P
@Chickenlordable true holograms are just reflections. Look at the hologram on a credit card. You can draw a normal hologram with computer controlled motors and a very fine needle. I only discovered that a very crude one will also work if made by hand.
@wbeaty No, true holograms work by putting an interference pattern on light that is passing through them. With a credit card, the hologram is put on a mirrored background, so the light passes through hits the mirror and then passes through again. Which is why credit card holograms look weird, compared to other holograms.
The thing in this video works by light glinting off an arc that's been scratched on the surface of the plastic.
@CecilTerwilliger Wrong, Benton or "rainbow" holograms don't work by interference, even though they are created using interference. That's why Benton holograms have no need for a monochromatic source. Wavelength independence requires size-independent fringes. Also we can make transmission or reflection holos in either Benton or off-axis type holos. Basic discovery: a Benton hologram with enlarged fringe spacing still functions. Make the fringe spacing be 1mm, and it still works!
@wbeaty I thought the purpose of the defraction grating on a rainbow hologram was to separate out the light into a spectrum so you get parallel bars of monochromatic light. The actual hologram(s) lie under the defracton grating. It looks to me like your hologram *is* the defraction grating. One made form arcs instead of straight lines. I'm guessing that the shorter the radius of the arc, the further form the plane the point it represents appears?
@CecilTerwilliger Yes, in all holograms the radius of the fringes determines positions of the image points. In this way an interference pattern is like a lens. But in normal holograms, the spacing of the fringes also affects the position of the image points. That's why light of a single frequency is needed. White light would turn images into rainbow blurs. But Stephen Benton at MIT invented a version where *only* the fringe radius determined the image points. Mine are Benton white-light holos.
@wasimsworld Generally, that's what you do first. Always check the description if you have questions about anything. If its not included in the description, then you ask.
@TheAdventuresClayMan see the project website. You have to go out in the sun. Sometimes it works great, but NOT UNDER LIGHT BULBS. Streetlights at night also work.
But if you still have problems ...avoid using sharp points. A dull nails works well, but a needle does not. If compass is too sharp, you must drag it very very lightly. Or attach a grungy nail to the compass.
Years ago I worked out a correct non-math explanation for how Benton Rainbow Holograms actually worked. Then in 1994 I noticed this strange effect with car hoods. It made me realize that I could create Benton Holograms by drawing curved scratches with a pointed stick. Ancient Greeks and Egyptians could have made these if they knew the trick. Or even cavemen.
I've read the site and I don't know if I'm convinced of the "true" hologram status, but what they truly undoubtedly are, is incredibly clever! :-) Well done!

My dad worked in a holography at the university of Michigan lab as a grad student, and when I was young he showed me how to do something like this, but lord, our little home project never turned out that well. bloody amazing. did you etch those paths by hand? how did you get the termination of the arcs so precise on the object-hidden-by-opaque-planes?
Thuringen 10 months ago
@Thuringen Just make about a hundred of these. I started out in 1994!
You do need good architect's compass. But also a dull nail point works much better than needle-sharp compass point. And slightly greasy polycarb plastic helps greatly.
The endpoint positions just use a simple trick I invented. Another trick lets me quickly create straight 3D lines. By cheating, I can become a human computer! See the main website, it's hidden in the SPIE 2003 "invited paper."

I read about this method a long time ago, about fifteen years ago, and while I understood what was meant to happen, I could never get it to work properly. The method I saw called for dividers scoring lines on acetate.
This is the first time I've ever seen it work, so kudos!

@JekyllsOtherHalf Dividers, but they can't be too sharp. (I use a nail in the dividers.) CD cases work well for the plastic

@Chickenlordable True thing
Kenckaplus 1 year ago
@Chickenlordable true holograms are just reflections. Look at the hologram on a credit card. You can draw a normal hologram with computer controlled motors and a very fine needle. I only discovered that a very crude one will also work if made by hand.
wbeaty 1 year ago 29
@wbeaty No, true holograms work by putting an interference pattern on light that is passing through them. With a credit card, the hologram is put on a mirrored background, so the light passes through hits the mirror and then passes through again. Which is why credit card holograms look weird, compared to other holograms.
The thing in this video works by light glinting off an arc that's been scratched on the surface of the plastic.
CecilTerwilliger 10 months ago
@CecilTerwilliger Wrong, Benton or "rainbow" holograms don't work by interference, even though they are created using interference. That's why Benton holograms have no need for a monochromatic source. Wavelength independence requires size-independent fringes. Also we can make transmission or reflection holos in either Benton or off-axis type holos. Basic discovery: a Benton hologram with enlarged fringe spacing still functions. Make the fringe spacing be 1mm, and it still works!
wbeaty 10 months ago
@wbeaty I thought the purpose of the defraction grating on a rainbow hologram was to separate out the light into a spectrum so you get parallel bars of monochromatic light. The actual hologram(s) lie under the defracton grating. It looks to me like your hologram *is* the defraction grating. One made form arcs instead of straight lines. I'm guessing that the shorter the radius of the arc, the further form the plane the point it represents appears?
CecilTerwilliger 10 months ago
@CecilTerwilliger Yes, in all holograms the radius of the fringes determines positions of the image points. In this way an interference pattern is like a lens. But in normal holograms, the spacing of the fringes also affects the position of the image points. That's why light of a single frequency is needed. White light would turn images into rainbow blurs. But Stephen Benton at MIT invented a version where *only* the fringe radius determined the image points. Mine are Benton white-light holos.

TheAdventuresClayMan 1 year ago
@TheAdventuresClayMan see the project website. You have to go out in the sun. Sometimes it works great, but NOT UNDER LIGHT BULBS. Streetlights at night also work.
But if you still have problems ...avoid using sharp points. A dull nails works well, but a needle does not. If compass is too sharp, you must drag it very very lightly. Or attach a grungy nail to the compass.

KittyCatAddict 1 year ago 8
@KittyCatAddict See the website!
Years ago I worked out a correct non-math explanation for how Benton Rainbow Holograms actually worked. Then in 1994 I noticed this strange effect with car hoods. It made me realize that I could create Benton Holograms by drawing curved scratches with a pointed stick. Ancient Greeks and Egyptians could have made these if they knew the trick. Or even cavemen.
