ABSTRACT:
An apparatus for generating a three-dimensional image including two unmultiplexed images in stereoscopic relationship with each other. One of the images is of a material reflective of a given wavelength of left-handed (or right-handed) circularly polarized light, while the other of the images is of a material reflective of the given wavelength of right-handed (or left-handed) circularly polarized light. The materials include cholesteric liquid crystals.
