1. A laser projection system comprising:

  • a laser source system configured to emit coherent light;

    an optical integrating system configured to uniformize coherent light it receives;

    a randomizing optical element configured to spatially move over time in order to temporally randomize the phase, angle or spatial location of coherent light it receives;

    an image forming system configured to interact with laser light that has been both uniformized by the optical integrating system and randomized by the randomizing optical element, thereby forming a laser light image; and

    a projection system configured to project the laser light image onto a viewing screen.
