ABSTRACT:
A color projector for forming a high resolution image through a plurality of stacked display panels. The projector employs subtractive color technology to project a real or virtual color image. In order to provide a highly focused image free from parallax effects, a dichroic mirror assembly is provided to reflect the light exiting the display panels and compensate for differences in optical path lengths between display panels while maintaining high resolution focusing capability. Light output averaging means are provided to eliminate additional parallax effects. High resolution optics are provided between the dichroic mirror assembly and the projection screen in order to provide focus for the image.
