Taranta, Austin (Inventors) (2016) Rotationally biased fiber optic gyroscope. EP3086091.
Abstract
A system for rotationally biasing a fiber optic gyroscope includes a fiber optic gyroscope assembly comprising a light source that emits an optical signal, an optical coupler in optical communication with the light source, and a fiber optic coil in optical communication with the light source.The fiber optic coil receives the optical signal through the optical coupler and imparts a phase shift proportional to rotation. A rate sensing detector in optical communication with the fiber optic coil receives the optical signal from the fiber optic coil through the optical coupler. A motor coupled to the fiber optic coil applies a periodic rotation to the fiber optic coil to impart a biasing phase modulation to the optical signal. A signal processing unit is coupled to the fiber optic gyroscope assembly and the motor. The signal processing unit converts a measured intensity of the optical signal to rotation rate data.
