Abstract
A steering mirror assembly operates in a stable manner with a high bandwidth, with one to two degree peak-to-peak angular stroke. The steering mirror assembly includes a mirror for directing signals to their destination by reflection. The steering mirror may be moved through any position in a cone of several degrees. Movement of the mirror is achieved by a number of actuators. The mirror is coupled to a flexure ring that locks out undesirable directions of motion. The mirror assembly also includes position sensor that indicate to the assembly where the mirror is currently positioned. Data from these sensors is used as feedback to appropriately adjust mirror position.
