1. A method for generating patterns to be used in a spatial light modulator having a plurality of pixels, the method comprising:

  • a) generating a pixel pattern to be placed upon the plurality of pixels of the spatial light modulator;

    b) applying the pixel pattern to the pixels of the spatial light modulator;

    c) measuring the optical performance of the plurality of pixels having the pixel pattern applied to it;

    d) comparing the measured optical performance to a target optical performance; and

    e) adjusting the pixel pattern applied to the plurality of pixels to form another optical pattern that more closely achieves the target optical performance.
