Abstract
Apparatus and methods for removing jitter and stabilizing the feed back system of a torsional hinged device with minimal changes to the system. The stabilization is accomplished by spatially isolating the pivoting mirror structure from all drive, support and packaging structures to reduce air drag. The mirror structures may be further stabilized by tailoring the drive mechanism and the position of the mechanism to produce substantially pure rotational drive torque on the mirror.
