Abstract: Disclosed herein are devices and techniques related to optical diffusers and particularly, diffusers to reduce moire patterns in a projected image. The device may comprise an array of micro-focal elements or reflectors and a light polarization grid. The light polarization grid configured to change a polarization between portions of a light beam and the micro-focal elements of reflectors to diffuse the light beam such that portions of the light beam having a difference in polarization may meet at a point.

Abstract: A micro-projection system for projecting light on a projection surface, comprising: at least one coherent light source (101); optical elements (102, 108, 109) in the optical path between said coherent light source and said projection surface; said optical elements including at least one reflective member (102) actuated by a drive signal for deviating light from said light source so as to scan a projected image onto said projecting surface; said optical elements including at least one vibrating element (102) actuated by a vibrating signal so as to reduce speckle onto said projecting surface. The corresponding method for reducing speckle is also provided.
