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 deviating light from said light source so as to scan a projected image onto said projection surface; said system including at least one pixel displacement unit for displacing the position of the pixel with respect to the position of a corresponding pixel in another image frame, so as to reduce speckle onto said projection surface, wherein said pixel displacement unit is arranged for controlling the coherent light source so as to modify the phase of laser pulses sent by said at least one coherent light source, so that the position of said pulses on said projection surface is modified by said phase modification.
