Abstract
Optical MEMS scanning micro-mirror comprising: —a movable scanning micro-mirror () pivotally connected to a MEMS body () substantially surrounding the lateral sides of the micro-mirror; —an transparent prism () substantially covering the reflection side of the micro-mirror; —wherein said prism has its outer face non-parallel to the micro-mirror neutral plane N-N, thereby providing a dual anti-speckle and anti-reflection effect, namely against parasitic light. The invention also provides the corresponding micro-projection system and method for reducing speckle.
