3D photographs produced by the interference of two laser beams, it is an advanced form of photography that allows an image to be recorded in three dimensions. The technique of holography can also be used to optically store, retrieve, and process information.
Comments:
The interference pattern from the laser etches an uneven pattern of color on the film. Sort of like microscopic ridges, but formed with the photo-reactive elements of the film. Because your eyes are offset to either side, your brain picks up the interference patterns from two different angles - thus the 3D effect.
Multicolor holograms can be produced as well, using 3 base colors: red, green, and blue. (Although blue lasers are expensive to produce.)
Most of the equipment you would need is easy to get, and very simple to put together. You can use a wooden sand table (that is, a table filled with sand) resting on solid cement foundation. (this minimizes the effect of vibrations by providing a solid surface and a semi-fluid platform.) Professional grade lenses, mirrors and prisms. Mounting hardware (such as that shown on the video) is cheaper.
