WebThe Traditional FOG The SiPhOG’s principle of operation is the same as that of the classical interferometric fiber optic gyroscope. In simplest terms, the phased modulated light is launched into a waveguide where the light experiences equal but opposite additional phase shifts during rotation. WebAnswer (1 of 4): The implementation of the fiber optic gyroscope is mainly based on the Segnik theory: when the beam advances in an annular channel, if the ring channel itself has a rotational speed, then the time …
