Advanced stereo projection using interference filters

— Stereo projection using interference filters is an advanced wavelength multiplexing approach that specifically takes into account the nature of the human eye, which is characterized by three types of color receptors. Accordingly, the filters used to code image information for the left‐eye and for the right‐eye image have three narrow bands each. Wavelength multiplexing represents a modern approach by overcoming earlier drawbacks in the color reproduction of image‐separation methods such as anaglyph technologies. Unlike polarizing technologies, there is no need of polarization reservation or a restraint to the projection technology.
