ABSTRACT:
An improved method of, and electrical circuit for driving with precision and accuracy an electro-mechanical device such as a galvanometer is disclosed. The method precisely controls high speed linear scanning of the device in a forward scan segment of each cycle of operation, and further provides very fast re-set of the device without position overshoot during a re-trace segment of a cycle. The electrical circuit includes memory means for generating an electrical command waveform for controlling the device during each cycle of operation, and drive servo means for applying electrical power to the device. The servoing action of this circuit substantially eliminates any difference between an actual position of the device and the position directed by the command waveform during each forward scan segment of a cycle of operation, with the result that each forward scan segment is highly accurate and repeatable. During each re-trace segment of a cycle the circuit re-sets the device at high speed in a way that limits accuracy destroying effects of device overshoot and oscillation.
