• EEVblog #103 – World’s Largest Depth of Field Laser Hologram

    Dave & Phil check out the world’s largest depth of field laser hologram display at Macquarie University.
    It was part of the Paula Dawson exhibition. The bar display is titled “To Absent Friends”
    This hologram was created in 1988 and is still the worlds largest to this day. They don’t make holographic plates this big any more!
    The resolution on this entire room display is incredible and was hard to catch on camera in the low light, but you can read the labels on the bottles as if they are right in front of you, and the light reflections in the crystal vases and other objects was simply amazing.
    See a behind the scenes video of how it was created here:

        Wow, amazing! Thanks for sharing, Dave!

      • Last 20 seconds the best.

        • Hahah, I just saw the last 20 seconds and…You’re definitely right. 🙂

      • That blows my mind.

      • When I was about 18 years old I trekked to NYC with some friends to visit a The Museum of Holography.

        A bunch of cool plates but the one you’ve shown us is awesome.

        And your reference to what passes for art – my city is littered with similar because we host the Rhode Island School of Design (RISD).

        thanks for letting us visit that place !

        I’d love to visit that place and see the holograms. I still have the holograms that I made in college, and I can appreciate how difficult those large holograms must have been to make. Vibrations ruin holograms so the objects in the scene have to be ‘holographed’ in a very quiet, vibration-free environment. I would imagine that developing film plates that large would be a project also.

        This video reminded me low tech “holograms”:

        simply awesome!
        Thanks for the tour Dave.

        That’s one very impressive set of holograms, which I saw in the US after they were first created. Very impressive holographic artwork for sure, but maybe not the “deepest in the world”. Conductron may have made some deeper in the late ’60s when they were first exploring holography. Same with Stanford. There are certainly holograms made with images focused out to infinity, but they aren’t “art” holograms and aren’t as large of recordings.

        By the way, film that size is readily available to be mounted onto glass if anyone would like to make such large holograms. Paula used a large Krypton Ion laser for exposure, also easily available.

        this stuff always makes me feel stupid when i hear the explanations. i have played with interferences of laserbeams in school, but i still don’t get it. very, very impressing.

        The level of detail is amazing. Makes me wonder how much information you could store if you adapted the technology into a digital storage medium. Perhaps a sliver a glass with an entire movie on it? More? Very cool stuff. Thanks Dave.
