Paper Abstract

Most laser scanning systems require that the angular position of the laser beam be controlled by a pivoted mirror with a diameter of several millimeters. The requirements of speed and accuracy with which this function must be fulfilled in most systems have led to the development of compact servo-actuated galvanometers of a novel design. Such devices are capable of rotating mirrors 7.5 to 30mm in diameter, through steps of 20 degrees, in times of less than 0.5 to 4 milliseconds, respectively. They have a positional linearity in excess of 0.1%, excellent shock and vibration resistance characteristics, and will operate free of maintenance for over 10" scan cycles. Current uses in newspaper photo transmission, engraving of printing plates, resistor trimming of thick film circuits, label marking and other scanning applications are described briefly.
