ABSTRACT:
Apparatus for deflecting a light beam, comprising: a scanning element having a base portion, a light beam deflecting portion, and a gap region disposed therebetween. The base portion is anchored with respect to an optical bench to permit the light beam deflecting portion to pivot about a fixed pivot point defined between the base portion and the gap region. The light beam deflecting portion has a natural resonant frequency of oscillation about the fixed pivot point and is mechanically-damped at the gap region. A permanent magnet and right beam deflating portion are mounted on the light beam deflecting portion. A magnetic-field producing coil produces a force field that interacts with the permanent magnet and forces the light beam deflecting portion to oscillate about the fixed pivot point at a controlled frequency of oscillation that is substantially different from the natural resonant frequency of oscillation of the light beam deflecting portion.
