man, the Holograms are epic.

one of the most amazing aspects of holography is the completely clear image of all objects achieved with absolutely no camera lens.

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

Thanks for sharing this. I'd have to assume a pulse laser was used to record those huge holograms. :)

Thanks for the support.

I have some posters which is vine bottle and the flowers.. It's insane.. After many years, bottle looks and feels same lol

Haha, "looks like they have let the Art students loose" Looks extremely similar to my university by the lake.

Imagine accidentally hitting and breaking the glass on Paula Dawson's hologram.🤣

@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.

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.

Ten to the eleventh power bits per square inch of film surface.

The ending made me laugh.

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

A bit better than the ones i made. My flim plates were 2 1/2" squares and 24 pcs of flim was around $200. Superfine Ag emultion. I am not sure what they used but I doubt it was a real bar. There can be no vibration at all and no light. The work has to be done on a vibration isolation table. Mine was 4' by 4', and I was doing single small objects. Amazing! They are very hard to make.

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

And just to think it was made in 1989!

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...

I want my money back; Dr. Phil did *not* make his promised appearance in this video.

Very cool, thanks for posting. :)

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...

How on earth does that work? The leather couch and glass vase at 1:03 appear to be reflecting/absorbing light the way they would if they were real. Especially the highlights! (Unless those aren't the current lights but the ones present at the time of exposure?)

If you divide to the hologram to 4 pieces or 100 pieces you still see full room from one piece. I know how to make it but still not fully understand how the light recorded on the film.

Funny thing is i actually like your accent and voice very much :) I just love it when you say "Don't turn it on, take it apart" :D

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

Amazing!

Very nice to see holography still present in some place in the world!. I've seen similar or even larger at a German Museum close to the city of Koln in 1990. Needs to say that the laser beam employed was a pulsed one, was'nt?

Doubt that you’ve seen laser viewable images of actual continuous physical area larger than these. John Perry made some 1 meter by 2 meter pieces for light artist James Turrell but the images were quite shallow and the physical holograms not nearly as large as Paula Dawson’s. It’s possible to make abstract mass produced holographically created imagery on rolls for packaging but that’s not real scene imagery like these single continuous images.

Crazy. Very strange.

brilliant

hologram are universe

@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".

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)?

Besides the cost being more than three times, the film is not sensitive to the three base wavelengths and there is no powerful pulsed lasers for blue, to my knowledge.

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...

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.

Kind of... The recording is limited to a plane the viewing angle is not 180 degrees. Each piece is a viewport but you can't see everything, and every angle, from a smaller window. Each section does not record all the information. Just what is viewable from it, at the maximum viewing angle. Hologram film is about 170,000 DPI ... so there is a lot of information in each small section.

Wow what a coherence-length this laser must have had at that time. When are that's a first generation white light holograme acyoly made? 1992 I made a second generation rainbow hologram this on a 16 tons optical table, it's little more challenge that to make a first-gen hologram this due to the fact that at this time the second generation wite light copy had to be made by a helium - neon laser with relative little power, about 100 mw, meaning a reductase long exposure time on the second-gen copy the first generation wears quud simple because it's made with a multiple jule ruby laser so if I remember right here I used a 7 nano-second pulse. Dont remember due to it wears not the laser I normally use in my own lab, actoly it wears the laser belonging to Dr. Martin Richtartsons so we I made it in the UK where he had this amazing 16 ton optical table so that's why I couldnt nake it in my own lab in the DK where I did live at that time. All the best the Tantric Holographour. 😃

Wicked

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

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

This... is this real? Found video explaining this in some way. /watch?v=XtvAhL1lzOI I know HOW, but don't understand WHY is it happening. This is great thing for curiosity. There's some quantum phenomenon underneath!

@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.

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

best part.check out that shit aaahahah

@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

It can be done in full colour,but temperature drift makes the whole scene rain-bowing and look like those cheap shitty id-card holograms.

Cut the bs guys! This is a pulsed-laser hologram. Anyone heard of absolute parallax?? Well, here it is .. Watch this video and watch it over and over again.
