ABSTRACT:
A phase spatial light modulator composed of a liquid crystal memory cell and a liquid crystal polarization switch. The liquid crystal memory cell having phase information recorded during the fabrication process thereby affecting the liquid crystal material contained within the cell. The liquid crystal polarization switch capable of perpendicularly rotating the polarization of light impinging upon the liquid crystal polarization switch, prior to passage through the liquid crystal memory cell in response to an applied voltage. The modulator, or scanner, thereby capable of modulating the phase of light passing therethrough, resulting in a high resolution resultant integrated image
