A two dimensional electro-optic modulator comprises an electro-optic element and a two dimensional planar array of individually addressable electrodes for spatially modulating a light beam along a plurality of transverse axes or for imparting a geometric phase front to the light beam. Such a modulator may be used, for example, (1) in a real time or in a time delay and integration mode as a multigate light valve for (a) electro-optic line printing or (b) optical displays, or (2) in a real time mode as (a) a beam focusing and tracking device for optical memories or (b) an areal input device, a Fourier plane filter, or an image plane correlation mask for optical processing.
