Motion of chopping mirror controlled very precisely by feedback circuit originally developed for mirrors in orbiting infrared telescopes. Mirror position and velocity electronically sensed and commanded. New controller enables selection of different chopping frequencies, angular amplitudes, dwell times, and dwell positions. Also reduces noise and vibration by eliminating mechanical stops and reduces energy consumption in actuator.
