Abstract
A monolithic triaxial ring laser gyroscope includes three orthogonal ring cavities, the optical path length of each of which is independently controllable. Three planar ring cavities are formed within a frame that is shaped into the form of a rhombic dodecahedron. A mirror is fixed to each of the twelve faces of the frame for directing the counter propagating light beams within the three orthogonal cavities. Anodes which communicate with the cavities through bore holes are fixed to predetermined surfaces of the frame while three cathodes are positioned at flattened portions of preselected vertices of the dodecahedron and located in such a way as to eliminate undesired bias resulting from Fresnel-Frizeau effects.
