MICRO-PROJECTION DEVICE WITH ANTI-SPECKLE IMAGING MODE

摘要

A micro-projection system for projecting light on a projection surface (104), 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 pixel displacement unit (106) for providing a displacement signal synchronized with the image scanning signal so as to reduce speckle onto said projecting surface. The corresponding method for reducing speckle is also provided.
