A stereoscopic display capable of displaying monochromatic or colored views of moving, three dimensional scenes comprises means for sequentially projecting alternate ones of successive pairs of substantially monochromatic images corresponding to right-eye and left-eye perspectives of the scene at a display rate sufficient to avoid a perception of flicker in the images. A variable polarizer is used to circularly polarize alternate ones of the images in respectively opposite senses synchronously at their projection rate. The images are analyzed by highly-transmissive eyewear comprising at least one pair of oppositely-sensed cholesteric liquid crystal circular polarizers tuned to the particular color wavelength of the images and disposed, one over each eye, to transmit appropriately-polarized images to corresponding eyes and to reflect inappropriately-polarized images away therefrom.

A stereoscopic display, comprising: projector means for sequentially projecting, at a projection rate sufficient to avoid objectional flicker, alternate ones of successive pairs of substantially monochromatic images corresponding to right-eye- and left-eye-perspective views of a scene, each said image having a wavelength of about Lo; variable polarizer means operated synchronously with said projector means for circularly-polarizing alternate ones of said images in each said pair in opposite senses; and binocular eyewear, comprising: a pair of circular polarizing elements having opposite senses, each said element containing a cholesteric liquid crystal material having a refractive index of about n and a pitch of about p, where nㆍpLo, and wherein said polarizing elements are each disposed within said eyewear to transmit corresponding ones of said polarized images to a corresponding eye, and to reflect oppositely-polarized ones of said images therefrom.
