An apparatus for generating a two-dimensional array of modulated light beams. A laser and a collimator (101) are used to generate a single collimated light beam (111). This collimated light beam is passed through a two-dimensional holographic beam splitter (102). Thereupon, the holograpic 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 (104). |
