Abstract:
1. A projector, comprising: a light source to emit illumination light; a color separation optical system to split the illumination light into illumination light with at least two colors; a plurality of spatial light modulators having an image-forming area to form image light by modulating the illumination light based on an electrical signal; a color synthesizing optical system to synthesize the image light formed by the plurality of spatial light modulators; a projection device to project an image light synthesized by the color synthesizing optical system; an irradiation optical system to irradiate the illumination light onto a region which is smaller than the image-forming area by converting at least one of a shape and a size of a light beam of the illumination light emitted from the light source; and an illumination-light scanning optical system to scan the illumination light emitted by the irradiation optical system on the image-forming area, a respective one of the plurality of spatial light modulators being disposed for each of the colors.
