Abstract
An optical assembly including a polarizing beam splitter (PBS) to receive a laser beam from a light source. A micro-electro-mechanical systems (MEMS) mirror disposed in a support structure of the assembly, wherein the MEMS mirror is rotatable and is configured to receive the laser beam from the PBS and to reflect an exit beam. A phase retardation layer deposited on the MEMS mirror.
