ABSTRACT:
A display optical system and an image projector incorporating the same. The display optical system includes a light source operable to emit light; a plurality of reflective light-modulating devices; a plurality of optical elements; a projection optical system including at least one refractive lens; and an optical curved-surface having a finite radius of curvature and interposed between the projection optical system and at least one of the plurality of reflective light-modulating devices, wherein the optical elements are arranged to guide light from the light source to the reflective light-modulating devices and to guide outgoing light from the reflective light-modulating devices to the projection optical system, and wherein the at least one refractive lens of the projection optical system projects incoming light to a predetermined plane.
