Abstract : An apparatus for effecting independent spatial amplitude and phase modulation of a light beam. Two birefringent crystal modulation means such as PROM's (Pockel's Readout Optical Modulator) are arranged so that the first modulation means spatially modulates the amplitude of the beam in accordance with an input image applied to the first modulation means while the second modulation means spatially modulates the phase of the beam in accordance with an input image which is applied to the second modulation means.
