Abstract
An optical projection system comprising a light source, a beam splitter module, a plurality of spatial light modulators, an optical combiner module and a projection lens is provided. The light source is used for providing a first white light. The beam splitter module is disposed in the light path of the first white light to separate the first white light into a plurality of second white lights. The spatial light modulators are disposed in the light paths of the second white lights respectively. Each spatial light modulator comprises a color filter to modulate each second white light into a color light carrying with corresponding color image signal. The optical combiner module is disposed in the light paths of the color lights to combine the color lights. The projection lens is disposed in the light path of the combined color lights after the optical combiner module to project the combined color light to be an image.
