ABSTRACT:
A resonant scanner mounts a mirror on a support that is torsionally compliant, yet stiff in the lateral directions. A torsion bar serves as the torsional spring that resonates with the rotating mass. One end of the bar is rigidly coupled to the mirror, the other end is clamped against rotation. The mirror support effectively prevents lateral movement of the mirror yet it has negligible effect on the resonance characteristics of the scanner. The clamping structure that secures the clamped end of torsion bar is stiff in the lateral direction and compliant in the axial direction, thus preventing lateral movement while accommodating changes in the length of the torsion bar which accompany its twisting action.
