Patent ID: 8004754

Claim:
An image generating apparatus, comprising: an image generating panel; illumination optical means having an intermediate face, said illumination optical means modifying beams of light in order to illuminate said panel uniformly and with a beam shape being congruent to the shape of said panel; means for deflecting a received light beam of primary illumination light having coherence properties to said illumination optical means, in order to irradiate said intermediate face with said light beam; and a projection lens configured to project an image received from said image generating panel, wherein said intermediate face is a face of a diffuser of said illumination optical means, said intermediate face of said illumination optical means is positioned in optical conjugation with respect to an aperture stop of said projection lens, and said means for deflecting deflects, during a process of irradiating said intermediate face, said light beam so as to subsequently in time irradiate different portions of said intermediate face, and to sweep said light beam in two dimensions across a pupil of said projection lens, so that light at any two locations within the pupil of said projection lens is incoherent with respect to each other.
