Process and an apparatus for correcting the measuring signals of a fiber optic gyro

摘要: In the case of a fiber optic gyro having 4×4-coupler, two arms coupler which are not connected with coil each monitoring detector. From output signals these detectors, in desired wavelength, reference or quotient is formed. During operation gyro, an actual formed from and compared stored quotient. The wavelength semiconductor laser controlled by controlling operating current and/or temperature light source (L) such that quotients identical. measuring will then be error free.
