Each of these areas can be optimized to meet program-specific requirements. Ball FSM optical surfaces range in diameter from 2.5 cm to 60 cm or various geometric shapes. The most sensitive of these mechanisms can respond to rate changes of more than 5,000 Hz, yet stabilize to within 0.1 microradians. Space-proven designs Reaction torque cancellation designs 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.
Ball can optimize the actuator design for applications requiring high accelerations.
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. Ball can optimize various parameters for specific applications or completely customize the FSM for customer-specific requirements.
