Abstract
Optical MEMS scanning micro-mirror comprising: —a movable scanning micro-mirror (), being pivotally connected to a MEMS body () substantially surrounding the lateral sides of the micro-mirror, —a transparent window () substantially covering the reflection side of the micro-mirror; —wherein a piezo-actuator assembly () and a layer of deformable transparent material () are provided on the outer portion of said window (); —the piezo-actuator assembly () being arranged at the periphery of the layer of transparent material (); —said piezo-actuator assembly () and transparent material () cooperating so that when actuated, the piezo-actuator assembly () causes micro-deformation of the transparent material (), thereby providing an anti-speckle effect. The invention also provides the corresponding micro-projection system and method for reducing speckle.
