Paper Abstract

The design of many optical systems presents the problem that the orientation of an optical path of relatively large aperture must be changed rapidly and accurately. When its speed is acceptable, the servo-actuated moving-iron galvanometer has proven to be an economical solution to this prob lem. This paper presents a discussion of the accuracy with which this device can provide beam deflection, with particular reference to linearity, repeatability, hysteresis and temperature drift errors.
