Abstract:
1. A projection apparatus for projecting a multicolor image, the apparatus comprising: (a) a light source for providing visible light; (b) a dichroic separator for splitting the visible light into color light beams; (c) illumination optics to direct each of said color light beams into a corresponding light modulation assemblies; (d) wherein each of said light modulation assemblies are similarly constructed and comprise: (e) a dichroic combiner which forms a multicolor image by overlapping said magnified real images from each of said color light beams onto a common optical axis; (f) a projection lens for projecting said multicolor image toward a display surface; and (g) wherein each of said polarization analyzers are tilted relative to a local optical axis and are located in proximity to at least one of said magnified real images of the color light beams.
