摘要:
According to one embodiment, a projection system includes a color wheel operable to filter light into a passed component and a reflected component. The projection system also includes a digital micromirror device comprising a plurality of micromirrors each operable to receive the passed component and the reflected component. Each micromirror is selectively positionable to direct, at approximately the same time, the passed component and the reflected component to desired locations. The projection system also includes an optical system operable to direct the passed component and the reflected component from the color wheel to the digital micromirror device at approximately the same time.
