ABSTRACT:
A positioning system including a sensor 52, a drive control 54 and an actuator 56. Sensor 52 senses a mirror 64 position and provides actual position signals to drive controller 54, which responsively adapts and applies drive currents to actuator 56. The actuator positions the mirror to reflect an optical beam 38 as desired. Preprogrammed sequences of mirror stopping positions can be synchronized with a laser 58 to tune pulses at very high rates and peak power.
