Abstract
Disclosed is a method for reducing speckling in liquid crystal displays with coherent illumination. The method consists of providing a liquid-crystal display illuminated, e.g., with a laser light, in which the image is formed by passing the light through the light redirecting holographic elements arranged in a matrix pattern, then changing the direction of the beams emitted from the holographic elements by passing the emitted beams through the polarization-changing liquid crystal elements, and converting the image-carrying beams produced by the liquid crystal elements into a visible image by passing them to a viewer through a polarization analyzer.
