ABSTRACT:
A path length control transducer assembly is created by utilizing an electrostatic drive to move a transducer. By placing a first electrically conductive plate to a driver, and placing a second electrically conductive plate on the movable element of a transducer, and then applying an electrical signal between these two electrically conductive plates, a force sufficient to move the movable element of the transducer is created. Placing an optical element or a mirror on the transducer movable element allows this transducer assembly to be used in a ring laser gyro for path length control.
