ABSTRACT:
A rotational sensing system for a Multioscillator 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, with the use of a local oscillator. The technique allows for rotational rate and direction detection, as well as cavity length control, with a minimum of cross-talk.
