The solid-state light valve, consisting of an off-axis electron gun and an electro-optic target crystal, is used as a two-dimensional spatial light modulator for a collimated laser beam. With a 1 mil electron beam spot and 50 μA beam current, 1000 line resolution and real time operation at TV frame rates have been achieved. The electron optics and three error function figures of merit for a generalized off-axis electron beam system are presented. The component selection procedure and an analog correction preprocessor design on a precalculated basis are discussed.
