Abstract:
1. A micro-projection system for projecting light on a projection surface, comprising: at least one coherent light source; optical elements in the optical path between said coherent light source and said projection surface; said optical elements including at least one reflective member actuated by a drive signal for oscillating the reflective member about one or more oscillation axes, so that it scans light from said light source so as to project an image onto said projection surface; said optical elements including at least one vibrating element actuated by a vibrating signal so as to reduce speckle onto said projection surface, wherein said vibrating element is actuated by a micro-vibration generator which provides a signal and wherein the micro-vibration generator is configured to electrically superpose said signal to the reflective member drive signal.
