Paper Abstract

Conventional ring laser gyroscopes (RLGs) are planar; the light beams are constrained to lie in a single plane. This need not be the case. We have found that nonplanar ring resonators offer certain advantages for the multioscillator (four frequency) RLGs developed by Raytheon. An overview is given of those properties of nonplanar rings which are pertinent to RLGs, including the inertial rotation sensitivity (the scale factor and the direction of the sensitive axis), the mode polarization, and the frequency spectrum. Design equations for a class of simple nonplanar rings are given and applications to multioscillator RLGs are discussed.
