This is our first step in providing the hologram machine itself to make your own holograms, rather than sending off to a service to make one for you. We think having this as a new tool, rather than just a service, will completely change access to hologram technology in the future, similar to what happened with 3D printing.

I appreciate your input as a holographer, and we are hoping to help create a lot more holographers in the future who will have access to their own 3D Hologram Printer.

Yes, there are definite applications for Holographic Optical Elements in this area. We are hoping that access to a 3D Hologram Printer will make development in this area even more accelerated. Thanks.

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.

Yes, the idea is to make this hologram technology more accessible and affordable, so that it is something you can use on a regular basis, not just a one-off occasionally.

Thanks! Will see how to highlight that better.

Thanks! We really do want to do this the right way, and grow the hologram community long term.

Let me know if you know anyone at Glowforge that could be a guide through the process. Always good to be able to bounce things off someone who's been there.

Sorry about that, it has been a crazy year, and things have fallen through the cracks occasionally. The holograms with our film do not form surface relief patterns, and would not work for the "press the hologram into chocolate" idea.

However, existing embossed holograms do have the surface relief and can be used for this.

I agree that holograms have a way of grabbing kids' imaginations! Perhaps you could get a 3D Hologram Printer as well and make your own hologram exhibit for the science museum. So the next generation of kids can get hooked.

The Chicogo Museum was amazingly packed with holograms practically floor to ceiling. The telescope one is another one to remember, with the front poking out into the viewer's side of the hologram, and the ability to put your eye up to is and see through.

Hopefully there will be a series of holograms made on our 3D Hologram Printer as an homage to older holograms like this that made an impression. That is what we were trying to do with our Kiss hologram.

Definitely possible. Essentially, each hogel could contain unrelated information and almost serve as holographic data storage.

Additionally, separate holograms could be tiled together to make a larger hologram as well. We even thought about having tiling as a stretch goal for the Kickstarter.

Holographic Optical Elements certainly have potential for applications like this, and the 3D Hologram Printer could be a great tool for simple prototyping and quick iterative testing.

Recently, Maimone et al at Oculus/Facebook Reality Labs used our hologram film to make a design for a thinner VR headset using pancake lenses incorporating holograms: https://research.fb.com/wp-content/uploads/2020/06/Holograph...

Razors or blades? Our first approach is to make the hardware more accessible and affordable (a first for hologram technology like this). But hologram film is the primary consumable. Has been interesting to see ink now become a subscription service as well.

The hologram film is laminated onto the glass for stability. The film itself is photosensitive and records the peaks and valleys of the interference pattern of the laser light.

Thanks! I appreciate the support.

We currently have a 0.5x0.5mm resolution as a Kickstarter stretch goal.

Where things like lenticulars do have fundamental limits concerning depth vs resolution based on diffraction limits, holograms do not have similar constraints.

Ultimately, there is no reason these holograms can't reach resolutions similar to print (and better). Following the 3D printing market examples, we chose to start simple and then build on that as we progress in the future.

Yes, SLM. We use an LCD which is then focused to the hogel aperture with the object beam, where it meets the reference beam at the film to record the hologram for that hogel.

Duly noted!

I saw the article (it got a lot of attention talking about holograms), but I didn't see any actual holograms. I hope they get a 3D Hologram Printer so that they can actually output their computations.

And go MIT!

And famous wizard cards! Now maybe you can make your own.

That's the idea! Hologram technology has a lot of untapped potential, and is still in early stages of growth.

These are reflection holograms.

Also sometimes called white-light holograms because they can be viewed with a regular spot light, sunlight, or even a smartphone flashlight.

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.

The microscope hologram is a cool one! Could definitely do something like that with our 3D Hologram Printer.

One of the other very memorable holograms out there is the Kiss, which is also possible (see our Kiss demo hologram).

I think holographic cameras would certainly be something that would be in the future for us. Glad to see you are already looking there!

That is a possibility!

We liked the hologram kits, but we needed something to take us to the next level with our hologram technology, and the 3D Hologram Printer is that step for us.

The hologram film continues to be available, and will be the same film we use for the printer.

Thanks! Yes, because these are true laser-recorded holograms the fringe pattern is quite high frequency. But the design of the 3D Hologram Printer greatly minimizes the issues and you don't need separate vibration isolation equipment.

Amen!

No, these are true-laser recorded holograms, capturing the interference pattern of the laser light. The current printer uses horizontal parallax only, but we do have full-parallax as a stretch goal for the Kickstarter.

We think bringing the technology to a level where you have the hologram printer and can work directly with it will be key in helping holograms go beyond where they have struggled before.

Similar to 3D printing, putting one in your workshop is different than just knowing that there is a workshop out there that will make one for you.
