Abstract:
An image display system, comprising:a light source emitting substantially unpolarized light; means for separating the substantially unpolarized light into a plurality of colored light beams; a polarizing element adapted to receive at least one of the colored light beams, to direct in a first direction a first portion of the one colored light beam having substantially a first polarization, and to direct in a second direction a second portion of the one colored light beam having substantially a second polarization; an imager adapted to impart image information on at least the one colored light beam and produce imaged light; a projection lens adapted to project the imaged light; and a polarizing beam splitter adapted to direct the first portion of the one colored light beam from the polarizing element to the imager, and to direct the imaged light from the imager to the projection lens.
