IMAGING DEVICE AND METHOD FOR ELIMINATING EDGE EFFECTS IN SPATIAL MODULATORS

摘要

An imaging device comprising an electro-optic modulator (5) for modulating incident laser beams; an array of adjacent electrodes comprising a group of imaging electrodes (6) addressed in accordance with image information; means (2) to illuminate an area slightly larger than the width of said imaging electrodes; and one or more additional electrodes (8) located on each side of said group of imaging electrodes to permanently direct extraneous marginal beams to light-stop means so that only the light emerging from the imaging electrodes is allowed to reach a light sensitive medium (11).
