Positioning system.

摘要

A positioning system includes a sensor (52), a drive controller (54) and an actuator (56). The sensor (52) senses the position of a mirror (66) and provides actual position signals to drive the controller (54), which responsively adapts and applies drive currents to the actuator (56). The actuator (56) positions the mirror (66) to reflect an optical beam (84, 86) as desired. Preprogrammed sequences of mirror stopping positions can be synchronized with a laser (58) to tune pulses at very high rates and at peak power.
