Abstract

A discriminant apparatus for laser angular rate sensors which provides an output signal related to a selected weighted vectorial sum of the coupling of energy between counterpropagating waves traveling about a closed-loop path. The discriminant apparatus is utilized in a closed-loop control system for minimizing the lock-in rate of the sensor and/or maintaining and selecting scale factor linearity.
