EEVblog #103 - World's Largest Laser Hologram with Dr Phil

[monkriddler]

Fantastic. I remember a local gallery had a hologram exhibition back in the early 80's. Is it possible to create a colour hologram using RGB lasers on a single photographic plate? Perhaps a pulse from each of the three colour lasers in quick succession (on a static object)?

[sirsideways]

Haha, "looks like they have let the Art students loose"

Looks extremely similar to my university by the lake.

[Films4You]

Leave you voice alone..

Ask Dr Phil about vibrations effecting Lasers.

Some Hologram making need tons of weight to stop any vibrations, or one light wave will be knocked out of reference

[natepepin09]

The ending made me laugh.

[linagee]

What's really cool about this is that even if we get super cool 3D technology (based on ICs and circuits), these may well last after 3D equipment fails. An IC based circuit will die once battery power or the entire electrical grid shuts down. These holograms could still be there thousands of years after! (If they are in a properly structured re-inforced building.)

[kiyotewolf]

ha ha.. could you imagine, having alot of those hologram room pictures, hanging up in the house, making the house seem like one, a haunted house, and two, like it's much bigger than it really is??

amusing.

[holojay]

And just to think it was made in 1989!

[EEVblog]

@holojay Yeah, and the plates are still in amazing condition!

[elektronickz]

Nice stuff. But i don't see how I could use this for my new design! maybe one day I create my own world in there that nobody is allowed to touch. hehe.

[CrashOrgasm]

Fan freekin tastic man. Yet again learning from eevblog

"Anything will pass as art these days!"

Haha, so true. What a freaking joke. Abstract art is ridiculous.

[stumpodeath]

Seriously man.... you need to remove the increasing upward inflection from the intro

[EEVblog]

@stumpodeath It's called a High Rising Terminal, and it's a natural part of my voice and Australian accent.

[Supermassively]

@EEVblog That's awesome that you're aware of the nature of your accent. I don't think most people think about it. You have to wonder how many Indians actually think about the sing-song tone of their accents.

[EEVblog]

@Supermassively My voice sucks, I know it, but I don't give a shit, it is what it is. I produce content, and those that criticise my voice or style etc don't produce anything, they just like to remain anonymous and whinge. They don't even realise they just look like spectacular fools. I won't get a radio announcer job any time soon - oh wait, I do have my own new radio show too!... Damn you gotta love the Internet! Publish and be damned.

[Supermassively]

@EEVblog Whoa there... you must be responding to the wrong person. I never criticized your voice. I LOVE Australian accents and all their little quirks. I just love when someone is educated enough in linguistics to analyze their own dialect.

[EEVblog]

@EEVblog Sorry, not directed at you, it was just a general rant to those like @stumpodeath who post stupid comments about my voice. I get it all the time, a shame these people don't "get it".

[Yeahitzbop]

@EEVblog Haha ya niggas get no pussy.

[Nanovirus5995]

@EEVblog I think its great. Nice to listen to and Everything you say makes it interesting. I dont know a lot about programming and complex circuits but I still watch the videos Mainly becuase of your soothing voice :P Keep it up.

[LegendofJonnie]

There are holograms like this at the Camera Obscura in Edinburgh, Scotland.

You can buy small ones (85mm by 50mm or so) too - I own a hologram of Spiderman mid swing.

I'm still waiting for the Holodeck to be invented, however...

[MAXKC1]

very cool!

Just keep the drunks out of there or they will be trying to walk through some of those panes.

[heroineworshipper]

She looks closer in age this time, but marriage to her looks harder than any EE problem.

[fknrdcls]

this should make the potential of holographic storage more obvious... the sheer amount of information stored in those plates is astounding.. and relatively easy to retrieve.

[SomeMoreVideos2468]

Very cool, thanks for posting. :)

[Wizard4592]

Bottoms up!!!

[fireraisr]

wow, that was wicked! I've never seen video footage of a hologram before, only stills. You really put it into perspective, pun intended XD

shoot now I need to research the DIY hobbyists that do this, curse you dave for bringing another cool aspect of physics into my world. Keep it up

[xXdenhartXx]

Amazing, thanks for the tour!

[hitachi088]

OMG !

this is so Amasing , i am stunned .

[freemind321]

how come the camera dosent pick up the hologram you were passing your hand through?

[Films4You]

Great... A liitle bit of time travel, well almost and a quite bar both of these are impossible LOL

Check out my Hologram play list :)

[timmylc]

DAVE! maybe im blind etc... but where was the $4.99 development platform you were talking about "in some vid i cant find now?"

YES ive been to your site but...

[killerman4ever]

@timmylc MSP 430 Launchpad.

[pikuorguk]

The bar scene was completely convincing on camera. The objects that appear to stand out from their displays looked quite strange.

When you looked into the rooms, could you destroy the illusion by seeing something equivalent to film grain or visual glitches? The fact it captured reflected images is very Blade Runner :)

One day this will be common and normal technology that everyone uses...

[EEVblog]

@pikuorguk No, the image had no grain or visual glitches at any depth, the clarity was stunning. A few darker patches due to the age of the plates but you have to look for them. It's not actually an "illusion", it's a real 3D holographic image recorded on the plates.

[hitachi088]

@EEVblog

this mean , a short sighted person can see clearly in the room without glasses ?

Amassing !

[Macka007]

@pikuorguk I think you can only get grain if the room is not absolutely still. Lasers tend to have a very short wave length, red ones I believe are around 320nm, so you can get very high resolution images.

Due to the tiny wavelength, holograms are very sensitive to vibration; I forget exactly how much it is, but I think the most movement allowable (when recording the image) is in the 10's of nm

[artifactingreality]

brilliant

[onlywhenprovoked]

That was very cool. I can see these being sold as high end art, recreating famous or historical rooms / scenes.

[killerman4ever]

That looks so awesome!

[sephiroth671]

lol at arts display at and....

[pikuorguk]

@sephiroth671 Yeah, that's art students for you. There's a bit of an art infestation near my parents' house.

[godhacker]

Amazing!
