Abstract
An optical image system includes an image projector and an image generator. The image projector has regions with adjustable brightness levels. The image generator generates an image received from a remote location on the image projector by directing first and second electromagnetic beams onto the regions of the image projector. The first beam changes the brightness levels of the regions in a direction, and the second beam generates the image by changing the brightness levels of predetermined ones of the regions in an opposite direction. Such an image system can capture, transmit, and display an image using an optical signal without converting the optical signal into an electrical signal and back again. Thus, the image system often provides a higher-quality image than conventional electro/optical image systems.
