Abstract
This paper reviews mechanical aspects in the development of a large, oscillating scan mirror mechanism that featured a remarkably low level of structural vibration for the impact energies involved in mirror oscillation. Another feature was that energy lost during impact was returned to the mirror by applying torque only during the instant of impact. Because the duration of impact was only about 0.010 second, it was critical that energy losses be minimal since there was not much time to restore them. Solutions to these critical mechanical problems constituted a major milestone in the development of object-space scanning sensors.
