<p>The image display system includes an illumination optical unit comprising a light source emitting light, and a dichroic mirror wheel composed of a plurality of dichroic mirrors, each of which is divided into at least three segments in order to sort out at least three color light beams from the light incident from the light source and reflect the light beams; an image optical unit modulating light incident from the illumination optical unit to form an image; and a projection optical unit projecting light from the image optical unit onto a screen. Since light is temporally and spatially divided, light loss can be reduced and high resolution of an image can be accomplished.</p> |
