Abstract:
1. A light source system for stereoscopic projection, comprising: a light source module for providing a first light beam and a second light beam; a color wheel module, having a rotary wheel, and the light source module being disposed at a first side of the rotary wheel, wherein the rotary wheel has a filtering region and a reflecting region, the filtering region and the reflecting region are symmetrical with respect to a radial direction of the rotary wheel, the filtering region and the reflecting region are disposed in a light path of the first light beam and a light path of the second light beam respectively, the filtering region is used to allow a third light beam of a first waveband included in the first light beam or the second light beam to transmit therethrough, and the reflecting region is used to reflect the first light beam or the second light beam; two reflectors, being disposed at a second side of the rotary wheel, wherein the second side is opposite to the first side, and the filtering region optically couples with the two reflectors as the rotary wheel rotates; and a multiband filter, being disposed at the second side of the rotary wheel and being disposed between the two reflectors, wherein the multiband filter optically couples with the two reflectors, the multiband filter is used to allow a fourth light beam of a second waveband included in the third light beam to pass therethrough and used to reflect a fifth light beam of a third waveband included in the third light beam, and the second waveband and the third waveband are contained in the first waveband.
