OPTICAL GYROSCOPE AND NOISE REDUCTION METHOD

WIPO Patent Application WO/2022/267970

A1

An optical gyroscope, which is applied to the field of detection. The optical gyroscope comprises a light source assembly (101), a first light beam transmission loop (105), a second light beam transmission loop (106), a first photoelectric detector (109) and a second photoelectric detector (110). The light source assembly (101) is used for generating a first light beam and a second light beam which are different from each other. The first light beam transmission loop (105) is used for transmitting the first beam in a clockwise direction while transmitting the second beam in a counterclockwise direction. The second light beam transmission loop (106) is used for transmitting the first beam in a counterclockwise direction while transmitting the second beam in a clockwise direction. The first photoelectric detector (109) is used for receiving the combined first light beam. The second photoelectric detector (110) is used for receiving the combined second light beam. The light beam transmission loops can simultaneously transmit light beams in opposite directions, such that the optical gyroscope can reduce noise during a detection process to improve the detection precision.
