Abstract
A system and method for producing an image having high dynamic range is described. The system comprises: a light source for providing light along an optical path; a digital micromirror device for directing portions of the light to off-state and on-state light paths, thereby producing an image; and a deformable optical element disposed in the optical path between the light source and the digital micromirror device for steering at least some of the light from the off-state light path to the on-state light path to increase dynamic range of the image produced by the digital micromirror device. The deformable optical element can comprise at least one steerable segment and at least one static element.
