1. A head-worn display device comprising:

  • a computer unit;

    at least one point light source mounted on the head-worn display device; and

    at least one spatial light modulator (SLM) mounted on the head-worn display device and operatively coupled to the computer unit;

    wherein light produced by the at least one point light source illuminates the SLM and gets modulated to produce modulated light, and the modulated light is directed on an exit pupil plane that includes a useful portion,wherein a light wave distribution within the useful portion is equal to a computed light distribution from a virtual scene,wherein the useful portion is steerable across the exit pupil plane to follow a motion of a user'"'"'s eye pupil relative to user'"'"'s eye when the head-worn display device is in use so that the user'"'"'s eye pupil acts as a spatial filter, andwherein the computer unit adds a controlled phase variation to the computed light distribution of the virtual scene such that speckle is reduced.
