ABSTRACT:
A crystal structure arrangement used in a spatial light modulator wherein an electrooptic crystal structure faces an electron beam source, such as a photocathode or an electron gun, within a vacuum envelope. Electrons emitted from the electron beam source in response to an image or image signal source are stored on the surface of the electrooptic crystal structure to form a charge image thereon and then to change the refractive index of the electrooptic crystal structure corresponding to the stored charge image. The refractive index change is read out using a laser beam or incandescent light beam.
