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.
