Abstract
A reactionless scanning and positioning system is disclosed which includes a mirror scanning assembly coupled to a reaction mass having a rotational moment of inertia equal and opposite to that of the mirror assembly, so that the system is effectively reactionless. The overall mechanical design of the scanning system is optimized to require minimum power consumption by the actuators used to drive the scanning assembly. The scanning assembly is mounted on flexible pivots having a torsional stiffness which provides a mechanically resonant frequency such that a minimum amount of power is required to angularly position the mirror. A position encoder disc is used in both coarse positioning mode and in a relatively fast scanning mode to determine the position of the mirror. In the present invention, the position of the mirror is accurately determinable in a fast scanning mode due to the novel mounting of the mirror with respect to the position encoder disc.
