1. A head mounted display for forming images in a user'"'"'s eye, said apparatus comprising:

  • a spatial light modulator comprising an array of pixels that can be selectively modulated to create a pattern;

    a light source outputting light that is split into first and second portions having substantially identical wavelength characteristics;

    first and second separate optical paths for said first and second portions of light, respectively;

    first and second reflective surfaces in said first and second optical paths, said first and second reflective surfaces facing different directions and being oriented to reflect said first and second portions of light to first and second sections of said spatial light modulator;

    imaging optics disposed with respect to said spatial light modulator to receive light from said first and second sections of said spatial light modulator for imaging said pattern formed by said spatial light modulator; and

    a head gear for supporting at least said spatial light modulator and imaging optics.
