WHITE LIGHT INTERFEROMETRIC FIBER OPTIC GYROSCOPE BASED ON RHOMBIC OPTICAL PATH DIFFERENCE BIASING STRUCTURE

WIPO Patent Application WO/2022/028281

A1

A white light interferometric fiber optic gyroscope based on a rhombic optical path difference biasing structure comprises a laser (9), a rhombic optical path difference biasing structure, a fiber optic loop (11), and a detector (10). The white light interferometric fiber optic gyroscope based on a rhombic optical path difference biasing structure uses an all-fiber optic structure, simplifies the complexity of a gyroscopic system, reduces the overall costs, and implements the linear output of a rotational speed signal using a white light interferometric demodulation algorithm.
