Abstract:
A crossed-flexure-pivot galvanometer having a tunable resonant frequency, said galvanometer comprising:(a) a base;(b) a plurality of flexures having first and second ends, the first end of each flexure being attached to the base;(c) a rotor comprising a permanent-magnet having radially facing magnetic armature poles, a shaft and a load connected to the shaft, the second end of each flexure being attached to the shaft, the flexures suspending the shaft within the base for torsional oscillation therewithin, the plurality of flexures, and the rotor collectively having at least one resonant frequency of torsional oscillation;(d) a stator having a center, the stator being adjustably attached to the base; and(e) means for adjusting the axis of the stator with respect to the axis of the rotor.
