1. An optics unit for capturing an image, comprising:

  • a means for directing image-reflected light to a spatial light modulator;

    a spatial light modulator (SLM) comprised of an array of reflective pixel elements, which are individually addressable and switchable, such that a series of pixel-reflected light beams are reflected from said SLM as different pixels are switched;

    a control circuit for addressing and switching said SLM;

    a means for focussing said pixel-reflected light to a photosensor; and

    a photosensor for detecting a single pixel-reflected light beam and for generating an electrical signal proportional to the intensity of said pixel-reflected light.
