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.

    Red Dot for WASR?

    Hey guys, I have a WASR10 AK47 and I'd love to attach a red dot or a holo sight. I am a noob when it comes to doing this, so I'm looking for some help. I was looking at the Trophy TRS-25 Red Dot, I'm just not exactly sure what I'd need to be able to install it on the rifle. Thanks
