1. A spatial light modulator (SLM) for modulating light incident thereon, the spatial light modulator comprising:

  • a plurality of pixels, each pixel including a plurality of phase shift elements; and

    a Fourier transform filter adapted to control the imaging system to resolve light reflected from each pixel but not light reflected from each phase shift element in each pixel,wherein the plurality of pixels are controlled to independently modulate phase and magnitude of light reflected therefrom.
