RING LASER GYROSCOPE WITH FIBER OPTIC BEAM COMBINER

摘要

Title of the Invention: RING LASER GYROSCOPE WITH FIBER OPTIC BEAM COMBINER Inventor: Bo Hans Gunnar Ljung An electromechanically dithered ring laser gyroscope includes a beam combiner utilizing optical fibers instead of conventional optics. This permits a beam measuring photodetector and associated electronics to be positioned outside the gyroscope or its enclosure. The invention further includes a dither compensator using optical fibers thereby replacing sensitive electronic or optical dither compensating components.
