Abstract:
An image projection system comprising an illumination system, a modulation system having at least two reflecting image display panels of the non-diffusing type for modulating light generated by the illumination system in conformity with image information to be projected, and a projection lens system, the image projection system comprising an element having a color-separating as well as a color-recombining effect, and a polarizing beam splitter which is situated between the illumination system and the element and between the element and the projection lens system, wherein at least one polarization-compensator is situated between the element and the image display panels and a further polarization-compensator is situated between the element and the polarizing beam splitter, and wherein said at least one polarization-compensator and said further polarization-compensator are configured to compensate for a change of polarization of light leaving the element.
