ABSTRACT:
One embodiment relates to a spatial light modulator (SLM) for modulating light incident thereon. The SLM includes a plurality of pixels, each pixel including a plurality of phase shift elements. The SLM also includes a transform filter adapted to control the imaging system to resolve each pixel but not each phase shift element in each pixel. The plurality of pixels are controlled to independently modulate phase and magnitude of light reflected therefrom. Other embodiments are also disclosed.
