Fiber optic gyroscope with closed loop and compensation of shupe biais

摘要

The dependent by the invention due to the optical path of light through a fiber coil (5) calculated and / or stored model by drift changes in a fiber optic gyroscope due to arising from temporal changes in the temperature Shupe effect is compensated, wherein the optical path in a VCO control circuit (16, 17, 18) is measured.
