Abstract:
1. A stereoscopic projection system, comprising: a first channel first stage imager and a second channel first stage imager, each configured to modulate polarized light input on a pixel-by-pixel basis proportional to gray scale values provided to each pixel of the imager, rotate the polarization of the light and reflect a matrix of modulated light pixels; a first channel second stage imager and a second channel second stage imager, each configured to modulate a matrix of modulated pixels of light on a pixel-by-pixel basis proportional to gray scale values provided to each pixel of the imager, rotate the polarization of the light and reflect a matrix of twice modulated light pixels; a relay lens system configured to focus the matrices of modulated light pixels from the first stage imagers on a pixel-by-pixel basis onto the corresponding pixels of the second stage imagers; a first polarizing beam splitter configured to polarize light input into oppositely polarized light inputs, direct the oppositely polarized light inputs onto the first channel first stage imager and the second channel first stage imager respectively, and direct the matrices of modulated light pixels from the a first channel first stage imager and a second channel first stage imager into the relay lens system; and a second polarizing beam splitter configured to direct the oppositely polarized matrices of modulated light pixels from the first channel first stage imager and second channel first stage imager onto the first channel second stage imager and the second channel second stage imager respectively, and direct the matrices of twice modulated light pixels from the second stage imagers into a projection lens system.
