Abstract

Attention is given to a family of single-mirror two-axis beam steering systems (TABS) developed for fine pointing control of an optical beam. The requirement is to control the line of sight of the optical system on board such a platform with sufficient bandwidth to overcome the perturbations and thus maintain the laser communication link between two satellites. The armature is supported on its center of gravity on a gimble. A balanced design is achieved with the mirror and tachometer magnets on one side of the gimbal and the torque magnets on the other. A negative magnetic spring constant which compensates for the angular restraining effects of the flexure bearings without any radial stiffness consequences is incorporated.
