ALEXANDRIA, Va., Nov. 6 -- United States Patent no. 12,460,931, issued on Nov. 4, was assigned to Anello Photonics Inc. (Santa Clara, Calif.).

"Mitigating bias instabilities in optical gyroscopes" was invented by Nathan Abrams (Santa Clara, Calif.), Mario Paniccia (Santa Clara, Calif.) and Mike Horton (Santa Clara, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "One or more phase modulators in an optical gyroscope operate on two counter-propagating beams to introduce a phase shift between the beams before the beams are interferometrically combined to generate a rotation signal. A signal generator generates first and second modulation frequencies to drive the phase modulators. The first modulation frequ...
