Abstract:
1. A solid state illuminator for a stereoscopic display, the solid state illuminator comprising: at least one first solid state light source for providing a first light beam with a first wavelength range; a wavelength conversion color wheel, comprising at least one first transmission segment and at least one first reflection segment; an actuator for rotating the wavelength conversion color wheel, wherein when the first light beam impinges on the first transmission segment, the first light beam passes through the first transmission segment and is converted into a second light beam with a second wavelength range, and when the first light beam impinges on the first reflection segment, the first light beam is reflected by the first reflection segment and is converted into a third light beam with the second wavelength range; a multi-band filter for allowing at least one portion of each of the second light beam and the third light beam to pass therethrough, and reflecting at least one another portion of each of the second light beam and the third light beam, wherein the wavelength ranges of the two portions are not overlapped; and an optical module for guiding the second light beam and the third light beam to the multi-band filter, such that the portion of one of the second light beam and the third light beam passes through the multi-band filter and reaches a goal position, and the another portion of the other of the second light beam and the third light beam is reflected by the multi-band filter and reaches the goal position.
