Abstract
Optical systems may include MEMS mirrors having elliptical mirror plates. A laser scanning system may include a MEMS mirror that scans an incident light beam along a single scanning axis. The MEMS mirror may include an elliptical mirror plate having a semi-major axis that is aligned parallel or perpendicular to the rotational axis of the elliptical mirror plate. The incident light beam may have an elliptical cross-section, such that the incident light beam completely or substantially overlaps the reflecting surface of the elliptical mirror plate. After being reflected by the elliptical mirror plate, the light beam may be circularized via one or more shaping lenses disposed in the optical path of the reflected light beam, prior to projection of the light beam.
