Abstract
Disclosed herein is a Pathlength Control Assembly for Ring Laser Gyroscope comprising, in a preferred embodiment, a mirror, coupled to a mirror housing including a mirror post, wherein the mirror is mounted on (or is an integral part of) an axially deflectable membrane of the housing. A pair of piezoelectric transducers are responsive to an electronic input signal and mounted to a backing plate. The transducers sandwich the backing plate and deform the backing plate to drive the mirror post to axially deflect said membrane. In this manner, the backing plate serves a dual function to both support the piezoelectric elements and drive the mirror post.
