  • Split-gain multimode ring laser gyroscope output optics detection system
    Patent number: 5157462
    Abstract: A rotational sensing system for a split gain, multi-mode ring laser gyroscope is disclosed herein that can operate with a simple upright symmetric optics mechanism, where the required signal separation is performed fully electronically. In a preferred embodiment, signal separation circuitry is provided which performs a 180.degree. or .pi. radians phase shift to one of a set of heterodyned signals, A.sub.in, and B.sub.in, with respect to a second set of Split Gain frequency signals, A.sub.out and B.sub.out, in order to extract these Split Gain frequency signals.
