Abstract:
A DMD illumination system having multiple illumination sources. A DMD illumination system is provided that includes a plurality of illumination sources, each of the illumination sources directing light onto the digital micro-mirror device corresponding to a respective position of an array of micro-mirrors, each illumination source being positioned to cause reflected light from the array of micro-mirrors to be projected out of the system, and 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 for turning each of the plurality of illumination sources on and off, so that the light from the plurality of illumination sources strikes the array of micro-mirrors and the light is reflected from the digital micro-mirror device and out of the system. Methods are also disclosed.
