Abstract
A compact, full color, light projection system using a liquid crystal light valve (LCLV) and a unique combination of optical devices. The LCLV operates to modulate a light beam which has been polarized by one of the optical devices. The modulated light beam is converged and registered by other optical devices to form the output image.
