Abstract
An apparatus for generating a two dimensional array of modulated light beams. A laser and a collimator are used to generate a single collimated light beam. This collimated light beam is passed through a two dimensional holographic beam splitter. Thereupon, the holographic beam splitter produces a two dimensional divergent array of diffraction limited collimated light beams. These light beams are then independently modulated by a two dimensional modulator array.
