Abstract
A phase spatial light modulator composed of a liquid crystal cell having molecular orientation recorded during the fabrication process as a direct result of a photochemical reaction exerted upon the liquid crystal material, a mechanically-induced change of a liquid crystal alignment layer, or by varying a plurality of polymer materials that compose the liquid crystal alignment layer, thereby affecting the liquid crystal material contained within the cell. The modulator, or scanner, thereby capable of altering the phase, thus steering light passing therethrough. During operation, the liquid crystal molecules deflect the light beam passing therethrough based on their orientation as recorded during fabrication when the applied voltage is 'OFF' or in an altered state when the applied voltage is 'ON'.
