These products employ modular designs that easily adapt to meet a complete range of system requirements. Ball has developed more than 25 different FSM designs since 1983. Component Description Ball uses a full range of substrate materials for the FSM optical surface. To prevent the FSM suspension from deform the mirror while holding it rigidly during operation, Ball utilizes patented flexures, flexure pivot suspensions or bearings, depending on the system requirements.
Ball can optimize the actuator design for applications requiring high accelerations.
Position sensing is accomplished through the use of non-contacting position sensors, which provide the needed closed loop performance without impacting the mirror surface. The FSM electronics include servo control, actuator drivers, and interface electronics. When necessary, a reaction torque cancellation mass can be included to reduce disturbance torques and allow stable operation independent of base motion. The following FSM chart specifications are typical. Other FSM configurations are available.
