OPTICAL INTERFERENCE REDUCING ELEMENT FOR LASER PROJECTION
First Claim
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.
