Optical Biasing of Ring Laser Gyroscope by Quantum Well Mirror,

reportActive / Technical Report | Accession Number: ADA319125 | Open PDF

Abstract:

The Quantum Well Mirror QWM is a semiconductor device fabricated from AlGaAsAlAs. It is composed of two structures, a back surface mirror and a front filter. The purpose of the QWM is to optically bias the ring gyroscope RLG out of the lock-in region. This is accomplished by shifting the apparent plane of reflection within the QWM by applying a voltage to the electrodes which control the optical filter. This device will reduce cost of the RLG by Removal of the mechanical dither hinge assemblies Removal of the high voltage circuitry used to drive the dither hinge Removal of the path length controller assemblies. Loosening of the performance requirement for the inertial sensor assembly ISA shock mounts. Increased reliability resulting from the removal of all mechanical assemblies in the RLG system.
