Abstract
A phase spatial light modulator composed of a liquid crystal cell and a liquid crystal polarization switch. The liquid crystal cell capable of creating a liquid crystal phase prism under the influence of an external voltage. 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 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.
