Abstract
A Fast Steering Mirror (FSM) of large diameter has been designed, built and tested. In order to make continuous tracking ability without loss of a target image, the FSM should be equipped with a large scale mirror for a wide field of view and require a high control bandwidth to reduce the tracking error. The design intricacies and trade-offs among various parameters of the FSM of large diameter to meet the desired goals are discussed. Finally, this device steers the large aperture mirror about two axes, achieving the operating range of 1mradian and a small-signal closed-loop bandwidth up to 500Hz which is greater than the structural resonance.
