Dampening system for micro-deflector scanning beam modulator

摘要

A micro-deflector comprised of one or more flexible reflector fingers athwart the path of a beam of high intensity light in a raster scanner, the fingers deflecting on the application of a bending potential thereto to guide the light impinging thereagainst along a different path, together with means to speed up restoration of the fingers to an undeflected quiescent position following removal of the bending potential through the application of a dampening potential to the fingers as the fingers approach the undeflected position.
