ABSTRACT:
An anamorphic lens (11) for use in a display system (10) that has a spatial light modulator (12) and a projection lens (13) and that projects images to a screen (14). The anamorphic lens (11) is placed between the projection lens (13) and the screen (14). The spatial light modulator (12) generates an image that is anamorphically squeezed in the horizontal dimension, and the anamorphic lens (11) widens the image so that the viewer perceives a normal wide-screen image on the screen (14).
