Abstract
A device for reciprocally rotating an output element such as a scanning mirror by means of an electric motor employs a two-degree-of-freedom suspension in which the motor armature is constrained by a first torsional suspension and the output element is supported from the armature by an independent second suspension. The resonant frequency of the armature and its suspension is substantially equal to the resonant frequency of the output element and its suspension.
