Abstract:
1. An image display system comprising: a light source for providing a beam of light along an illumination path; a recycling integrator having a mirrored input aperture on said illumination path for homogenizing said light beam; a sequential color filter on said illumination path for filtering said homogenized beam of light; a polarizing beam splitter on said illumination path for receiving said filtered beam of light at a first face, separating said filtered light beam into a first beam having a first polarization state and a second beam having a second polarization state; a first spatial light modulator proximate a second face of said polarizing beam splitter receiving and selectively modulating said first beam; a second spatial light modulator proximate a third face of said polarizing beam splitter receiving and selectively modulating said second beam; a total internal reflection prism assembly proximate said first face and on said illumination path and a projection path to separate the illumination and projection paths; and at least one projection lens on said projection path for focusing said first and second beams on an image plane.
