ABSTRACT:
A light modulator is described which generates an output optical field from an input optical field. The light modulator features first and second polarization-rotating elements which are directly attached to one another. Each element contains an array of pixels including liquid crystals aligned along a specific axis. During operation, the pixels are biased to rotate the liquid crystals. For a particular polarization, the phase and amplitude profiles of the input optical field passing through the pixel array can be arbitrarily and independently controlled across an aperture of the light modulator.
