Methods and Apparatus for Illumination with DMD and Laser Modulated Adaptive Beam Shaping

摘要

Illumination with DMD and laser modulated adaptive beam shaping. A DMD illumination system includes a plurality of laser illumination sources, each of the plurality of illumination sources directing light onto a phosphor arranged between the plurality of laser illumination sources and a digital micro-mirror device; control circuitry coupled to the plurality of illumination sources and to the digital micro-mirror device configured for controlling the position of the array of micro-mirrors and further configured for providing control signals to each of the plurality of laser illumination sources, so that the light from the plurality of laser illumination sources strikes the phosphor and is then directed from the phosphor onto the array of micro-mirrors in the digital micro-mirror device when the micro-mirrors are at a predetermined position, and the light is reflected from the digital micro-mirror device and out of the system. Methods are also disclosed.

1. A DMD illumination system, comprising:
a plurality of laser illumination sources arranged proximate to a digital micro-mirror device, each of the plurality of illumination sources directing light onto a down converter material arranged between the plurality of laser illumination sources and the digital micro-mirror device; control circuitry coupled to the plurality of illumination sources and to the digital micro-mirror device configured for controlling the position of the array of micro-mirrors by applying one or more control signals to the digital micro-mirror device, and further configured for providing control signals to each of the plurality of laser illumination sources, so that the light from the plurality of laser illumination sources strikes the phosphor and is then directed from the phosphor onto the array of micro-mirrors in the digital micro-mirror device when the micro-mirrors are at a predetermined position, and the light is reflected from the digital micro-mirror device and out of the system.
