Two suggestions for your site: • Knock off the first 30 seconds of your 'interior shots' video where the machine is presumably registering itself. I don't much care about that :) • Show the resultant printed film from the side on somewhere, so we can see how thin it is. From first glance, I got the impression the output was quite thick, whereas apparently it's only 16 microns (taken from your spec sheet). It might seem obvious to you, but it wasn't here and I think would be much more impressive. Neat tech, I've forwarded it to someone who might have use for it. Good luck!

Thanks! The film plates are on 2mm thick glass, and the actual holographic recording layer is 16 microns, with a coversheet material over that.

  Can the layers be side-illuminated? If so, could these be layered, with some compensation for angle employed to account for depth, allowing you do fake RGB? ed - eg. each 16 micron sheet is side-illuminated with a specific colour, and then three or more holographic sheets are embedded in between the glass plate and cover?

    Our LitiHolo hologram film is full-color sensitive, and the finished holograms are transparent, so layer is possible. We've started with a printer that is single-color initially to get this off the ground, but eventually we would like to have a full-color version of the printer in the future with RGB recording directly in one layer.

  I agree with the feedback of having a picture better capture the thickness of the holograph plate (or whole assembly, whatever that's called). From the Buzz Lightyear picture I got the impression that it would be something like a thick picture frame, but that doesn't match the 2mm description. Would it be possible to use these as badge photos? I feel like it would be pretty cool to have a hologram picture on your badge.

    The glass film plates keep the film stabilized for the hologram exposures, but it is possible to peel the film off after recording the holograms. Will work on seeing if we can get better imagery of the hologram thickness.

    Yuri Denisyuk's original concept for wavefront reconstruction was to make a little 3D ID picture of a face, inspired by a Russian sci-fi story.

      Denisyuk is one of the fathers of holography (his hologram technique was one of the first to allow white-light viewable holograms, also called reflection holograms). Along with Gabor, Leith, Upatnieks, and my professor at the MIT Media Lab, Steve Benton.
