Holography Lecture by Thomas Grillo

This video features a lecture on industrial applications for holographic imaging. This video features a musical soundtrack consisting of theremin performances by Thomas Grillo, and piano accompaniments by Kristian Banatzianou, and Peter Nagy with their kind permission. This video was recorded at Mississippi Public Access Studios in January of 1997, and is copyrighted 2008 by Thomas Grillo

Thomas, did you add the Theremin-music after having digitized the video, or were you a theremin-player way back in the nineties as well?

I'd also like to ask what the motivation for making this video was in the first place. Did you have a business that you were promoting? Was it commissioned by someone? Or did you look into the future, sensing the vast possibilities of the Internet and simply will this thing into being?

Thank you SO much for all your wonderful videos, Grillo.

@kisakk Thank you. The music was added to the video recently. As it was, the original video was a exciting as that guy who did the eyedrops commercial, and principal in Ferris Buler's Day Off. Had to do something. I shot this video back in the early 90s when I did have a business making holograms. It was originally intended to be, and did run on the public access channel in our area. It was also going to be marketed on dvd in a limited form at the time for educational puposes.

its like 'This Old House' did a few micro dots

I'm sure you're refering to the grainy, fuzzy resolution. :)

This video was shot on VHS in the mid 90s, and copied from a master which I nolonger have as it deteriorated. Thie video from which this video was produced was nearly oxidized too.

In just a few more years, the one copy that remains on VHS will have oxidized completely, and I'd never have been able to produce the video. This, and the dvd it's now backed up on is all that will be left in a few more years.

You're welcome.

Fascinating, Thankyou Sir. :-)

...further, There are 360 degree holos of objects which were simply placed in the center of the film holding drum, and imaged directly as a hologram. There is only 3D parallax, and no movie animation.

I recommend you consult the book "Holography Handbook" for far more information which will help you build a deeper understanding of holographic imaging.

[ThomasGrillo]

...Further, The movie Logan's Run used 360 degree holograms as props for the interrogation scene in the movie.

These holos were produced by American Bank Note.

360 degree holos resemble an empty drum in the center of which is the reconstructed vertual image of the subject.

Conventional holos which are not produced using movie or video frames, where the model is holographed directly on a flat film only produce a 50 or 70+ degree field of view around the object.

[ThomasGrillo]

Lenticular images which use a lens sheet to distinguish between two, or more 2D images interlaced on a sheet of paper, or film work like this.

They, and certain types of holos (movie holos) can in fact display an animated sequence of an angel you wish after the subject has been filmed with conventional movie or video gear. Individual holos of each frame are recorded holographically.

There are also 180, and 360 degree holos which have been around since the 70s which use this same technique.

...con't

a bit of thinking to do to even figure out what's going on here. I suspect we are seeing a 3d 'looking' image coming from 2 dimensional surfaces which have differing images recorded onto it which will be apparent when viewed from different angles. Like the lady in one image and then she is wearing a bathing suit if you view from a different angle.

Actually 2 pictures on 2 different 2 dimentional planes.

I'm really not sure you can get a 180 degree back side view from this.
