摘要：A method and apparatus for reading out angular rates by means of a passiveoptical resonator provides for the generation of three component light beamsindividually tuned to distinct resonator modes. One component light beam is radiatedinto the resonator in the opposite direction to the two other component light beams. Bymeans of an evaluating logic, differences are formed between the counterrotating lightbeams and the differences weighted and subtracted from each other to provide angularrate. The optical length of the resonator, and, thus, temperature are available as aweighted sum of the differences. Temperature drift may be eliminated from angular ratemeasurements by compensation according to the invention.
