Abstract
An imaging system using a spatial light modulator has first color laser light directed by a dichroic element to a rotating member. The rotating member includes phosphor segments that respond to illumination by the first color light to emit second and third color light along a first path to the dichroic element for output, and a light transmitting segment that passes the first color through the rotating member along a second path to the dichroic element for output. In a 3D imaging mode, the first color laser light includes light of two wavelengths, and the phosphor segments include segments that emit second and third color light each of two wavelengths. The output light is directed to a second rotating member that selectively transmits one wavelength of each color while blocking the other wavelength of each color.
