摘要： A light energy source (20) produces low intensity light. The low intensity light rays are made substantially parallel by collimating lens (30). Filter (32) is placed to receive light from collimating lens (30), and to pass wavelengths to which a photoconductor in light valve (34) has maximum sensitivity, and to absorb or reflect other wavelenghts. The filtered, collimated light propagates through aperture mask (36) and is focused into the pupil of the matrix modulator (38) by lens array (40). The focused light is amplitude modulated by the matrix modulator (38). A lens array (42) collects light from the matrix modulator (38) and relays it to the photoconductive surface (44) of light valve (34). Thus, the illuminated image of the aperture mask (36) is magnified at photoconductor (44).

摘要： An active matrix liquid crystal light valve is disclosed. The addressing matrix has an array of electrodes (33) to create electric fields across the liquid crystal layer (90). A continuous nonconductive reflector layer (75), separate and distinct from the electrode array (33) of the active matrix enhances brightness, contrast and manufacturability. This light valve has a leveling layer (73) disposed on the active matrix to form a planar surface. The reflector layer (75) is formed as a continuous sheet on the planar surface of the leveling layer (73). An additional invention is the use of fringing fields to switch substantially all of the liquid crystal (90), including areas not directly over the electrodes (33).

摘要： An optical system having a projection lens (18) for imaging a scattering type thermo optic cell (16) on an image receiving surface (22), comprising optical source apparatus (12) for generating an optical beam and an image created on the scattering type thermo optic cell (16) having a minimum feature size, the optical beam propagating through the image on the scattering type thermo optic cell (16). Also provided is a condenser system (14) which illuminates the scattering cell (16) and underfills the aperture (24) of the projection lens (18), thereby creating a partially coherent imaging system. As a result, a relatively higher contrast ratio for the minimum features of the image is obtained as the image receiving surface.
