    摘要: 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.

    摘要: 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 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 are mounted within a driver housing and drive a driver post which is made from a thermally expansive material. As the backing plate is deformed to drive the mirror post to axially deflect the mirror membrane, the central driver post passively expands in response to temperature changes. In this manner, the transducers and thermally expansive mirror post act in conjunction to both actively and passively drive the mirror post over the full dynamic range of multioscillator or other ring laser gyroscope.
