holographic
Holography is a technique that enables a wavefront to be recorded and later re-constructed. Holography is best known as a method of generating three-dimensional images, but it also has a wide range of other applications. In principle, it is possible to make a hologram for any type of wave.
A hologram is made by superimposing a second wavefront (normally called the reference beam) on the wavefront of interest, thereby generating an interference pattern which is recorded on a physical medium. When only the second wavefront illuminates the interference pattern, it is diffracted to recreate the original wavefront. Holograms can also be computer-generated by modelling the two wavefronts and adding them together digitally. The resulting digital image is then printed onto a suitable mask or film and illuminated by a suitable source to reconstruct the wavefront of interest.
I have a Bushnell holosight made by EOTECH and is was made to go on a Bow but it works and mounts just like any other eotech. I also have a new EOtech hood to go on it and a new Knurled knob and new hood screws and new battery case. It does not have a elevation adjustment screw because the bow...
Hey y’all!
For sale is an EXPS 2-0. Great shape, clean glass, hung out in the safe a lot, 500 rounds ish (one carbine class) with it. It’s so damned hard to get a photo of the stupid reticle. It’s clean. Promise.
Anyway, box, papers, the whole thing. Let’s shoot for $400 here--I found my...

What's the difference? I have a vortex sparc and like it but I need a second sight for another AR. I do have a slight astigmatism and the dot on my sparc is kind of starry but it doesn't bother me much. Reason I'm curious about the difference though is I have a chance yo get an eotech 512 for...
This is a holographic projection of a Whale. It is a photographic process that produces images thanks to the differences between 2 laser beams.
These images are projected into a gym using a special camera. There is not a drop of water in this room, let alone a whale...
Looking to trade my EOtech setup. Both the 552-A65 night vision compatible optic and G33 3x magnifier are like new and both come with factory cases and paperwork. The 552-A65 comes with flip up lens covers, not shown, the and magnifier comes with the quick flip to the side mount. Mainly looking...
