Abstract
An image display system and method provides at least two separate and distinct images of a viewed scene for an observer. The images, taken from adjacent positions looking toward the target scene, are taken from relatively small, acute position angles with respect to the scene. These separate images are then encoded with different polarization in sequence for displaying on a television monitor. The images are prepared for viewing by an observer by focusing the monitored images onto a liquid crystal light valve. Collimated light from a coherent source addresses the light valve providing a coherent output therefrom with the encoded images thereon. These images are brought to a Fourier plane and polarized or filtered selectively to provide separately encoded images in alternate frames of polarization. An observer wearing separately polarized lens and viewing an output screen sees a stereoscopic view of the imaged scene.
