Hologram of a Lens

- Inspired by the well-known, art hologram, "Digital," created by physicist Nick Phillips in 1978 and featured in the MIT Museum Holography Collection, we decided to create our own hologram with a magnifying glass. It's pretty cool! The hologram still records the magnifying properties of the lens and displays the tiny letters of the circuit board behind it.
Take a look and then create one for yourself with your own Litiholo Hologram Kit. Just remember to let us in on what you create by using #litiholo in your social media posts.
they will use holographic lenses with the next gen vr glasses . exciting times
Yeah hope they got no godrays xD
I have several cool holograms I've shot with the kit. I really need to go ahead and upload them. Hope y'all have recovered from the water heater flood incident, and are back in action. :)
Now I'm wondering what would happen if you use a mirror instead of a magnifying lens.
It works like a mirror and watched with white light its a nice grating that mirrors a narrow band of the spectrum, see my videos for a sample
@@sonnenklang6925, when you say "works like a mirror", do you just mean it reflects objects that were there when the hologram was made, or that it reflects real objects eg reflecting yourself looking at the mirror?
@@JNCressey jes it reflects the same like an real physical mirror but only one color in this case.. if recorded in rgb laser light u get a almost real mirror .. :)
@@sonnenklang6925, That's cool. Thanks
@@JNCressey u r welcome ;)
and checkout my hologram videos ,thx
MIND BLOWN. So cool!
Man I would give anything if I could justify the cost of your color upgrade kit! I’ve watched the secondhand market for years since they came out and never found one. I have a few of your regular kits and stacks of your film. I’ve got dozens of lasers, I bought out an old college optics lab at a machine shop auction… Got a big nice breadboard, optics table, mounts, and all of the lenses and stuff. Just need the darn upgrade kit. I love your stuff!
Amazing, this truly is incredible
I remember making a hologram of a lens, in front of a medicine bottle, when I took the holography symposium at Lake Forest University, in 1991. It was an 8x10 holo, made using a 40mW HeNe laser. This is very cool. Thanks for sharing this.
Will this hologram only be visible under laser light or will it also appear on the glass under lamp light?
@@retrobudapest This particular type of hologram, which is a transmission hologram, can only be seen by shining a spread out beam of laser light into the hologram, at the same angle at which the original recording setup's beam of laser light was shined into the glass plate, and bounced from the real object. However, to make a white light viewable hologram (ordinary light), you would place the film glass between the object, and the laser, and record the scene that way. You would then be able to stand with the hologram in front of you, and the ordinary, point source light above, and behind you, shining into the hologram, at about the same angle as the recording beam entered the film, to be bounced off the object, back to the plate. :)
@@ThomasGrillo Thanks for the quick answers!
Is it possible to create a hologram on smooth positive color film with a laser or is it too thin to record the hologram data?
In the triangular arrangement, as in the video, couldn't the holodisk be replaced with an ordinary Polaroid film?
Do all holographic films have to be transparent?
On Ebay, they sell pictures that are on non-transparent film and real holograms that can be seen in white light. Are they glued to some kind of paper and that's why it looks like that?
Are holograms so expensive because they cannot be duplicated? Are each hologram recorded in a studio with the miniatures?
@@retrobudapest Holographic film or plate emulsion has to be at least 5 microns thick, compared to the thinner conventional photography film. Holographic film is transparent. For white light viewed holograms, it's recommended the back be blackened with paint. Or, the hologram can be mounted with black velvet behind it. Transmission holograms are kept transparent. Most holographic recording emulsions are silver halide, dichromated gelatin, or photopolymer. I think X-ray film has even been used at one time, though they didn't produce particularly bright images. Conventional film won't work.
@@ThomasGrillo Is Polaroid instant film also thin?
So in holography, thin film technology is not used to create images?
This is Mindblowing, I NEED THIS
so dang cool.
FANTASTIC! I made a few holograms of a lens in front of an old 286 PC circuit board, back in the 80s on Agfa film, using a HeNe laser. Amazing to think we can now do this so cheaply, and yet still have such beauty be rendered on the Litiholo kit. Thanks for sharinthis.Oh, have you tried making an H1-H2 setup for white light focused image reflection hologram of this scene?
Yeah, we had a lot of fun making it. Thanks for the comment! We haven't got around to trying out higher levels of H1-H2 yet, but would love to try it with some of the other kit accessories.
ThomasGrillo what kind of agfa film you used?
Thats pretty nifty there. When can i order a kit ? Mi missed the order window
From years back, I wonder about this lens effect, is the hologram just putting out static multi angles of a lens or is the lens really acting as a lens. The best way to prove this theory is moving the entire hologram back and forth on the z axis while looking through the lens. or have two lens and background image interact with each other in the same hologram.
I'm wondering the same thing
@@WillTesler yeah, I would like to see more studies on this. What would be really nice is to make a static hologram drive or interact with a digital hologram. For starters have a holographic lens project an Image from the real world into the holographic film itself. That would shut me up. BTW I created digital holograms.
obviously the captured image has a constrained z-axis.
@@h7opolo after understanding more about this form on holograms. It's more of a super position of every angle that's presently available. Yes its constraints in its numerous but limited available angle. And it's just an illusion using micro trianglutions by creating and baking Crystal like material. Like little mirrors. The hologram only captures reflection and not the actual characteristics of a lens.
You can record, create a holographic lense element tho, its just the simplest hologram of a pointsurce, showing only concentric rings in a specific pattern
Is it possible to create such full-colored holograms by using of revolving-framed or fiber-coupled DPSS 659nm, DPSS 589nm, DPSS 532nm, DPSS 479.5nm, direct-diode 445nm and 405nm? Can it be exposed continuously/simultaneously on single photoplate or this requires more sophisticated technique?
I'm thinking of getting one of these kits. Is the laser required to view the hologram though? Can it be viewed in natural light?
Also, I have a few different lasers already, if I set them up would I be able to capture a hologram using these and their different colours?
With transmission hologram, yes you need the LASER. But you can take reflection and rainbow holograms as well...
