20110149362 | TILTABLE MEMS MIRROR - A MEMS mirror is disclosed having thickness correlated with the intensity profile of an impinging optical beam, so as to reduce moment of inertia of the MEMS mirror while preserving optical quality of the reflected beam.

Accordingly, by providing a mirror having laterally varying thickness matched to the local variation of the intensity of the optical beam, the quality of the latter may be preserved while the moment of inertia of the mirror may be significantly reduced. The thickness of MEMS mirrors may be varied continuously or stepwise; in one direction or in two mutually orthogonal directions. | 06-23-2011 |
