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° or π radians phase shift to one of a set of heterodyned signals, Ain, and Bin, with respect to a second set of Split Gain frequency signals, Aout and Bout, in order to extract these Split Gain frequency signals.
