ABSTRACT:
A microchannel spatial light modulator that has a photocathode to receive incident light and to provide a spatial distribution of photoelectrons (herein called an electron image) whose spatial number density is proportional to the spatial intensity of the incident light. A microchannel plate is provided to receive the photoelectrons and to amplify the electron image. An electro-optic plate is provided to receive the amplified electron image; there is a dielectric mirror coating and an insulating light-blocking layer at one major surface thereof to receive the electron image and a transparent electrode at the other major surface thereof for biasing purposes. All of the foregoing elements are contained within a vacuum housing; suitable electrical potentials are applied to effect the necessary results. The modulator is capable of real-time phase or intensity modulation.
