Precision Fast-steering Mirrors Component Description Ball uses a full range of substrate materials for the FSM optical surface. To prevent the FSM suspension from deforming the mirror while holding it rigidly during operation, Ball utilizes patented flexures, flexure pivot suspensions, or bearings, depending on the system requirements and application.
Ball can optimize the actuator design for applications requiring high accelerations.
The FSM electronics include servo control, actuator drivers, and interface electronics. Both analog and digital interfaces can be accommodated. When necessary, a reaction torque cancellation mass can be included to reduce disturbance torques and allow stable operation independent of base motion.
