Abstract: A system and a method that isolate a payload from the effects of vibrations by providing an active feedback path that enhances the isolation performance of a passive vibration isolation system at all relevant frequencies. The system comprises a kinematic arrangement of three bipod pairs of hybrid isolation struts to produce a fully kinematic suspension system. The active enhancement mechanism incorporates accelerometer feedback on each of the six hybrid isolation struts, blended with relative displacement measurements, to produce a transfer function that provides a specified alignment of a suspended component (with another component) at low frequency, but inertial stabilization at high frequency. Passive roll-off is produced by a series of disc flexures in each hybrid isolation strut.

Abstract: A self-monitored controlled optical component system may include an electrostrictive actuator, a capacitor matched in capacitance to the electrostrictive actuator, a current source connected to the electrostrictive actuator and to the capacitor that supplies an electric current to the electrostrictive actuator and to the capacitor, an optical element connected to be moved by the electrostrictive actuator, and a comparator connected to receive a first output current from the electrostrictive actuator and a second output current from the capacitor, and output a differenced sensoriactuator signal proportional to the difference between the first output current and the second output current, the sensoriactuator signal representing a current associated with movement of the optical element by the electrostrictive actuator.
