VERFAHREN UND ANORDNUNG ZUM ERMITTELN VON WINKELGESCHWINDIGKEITEN

摘要

A process and device are disclosed to measure angular speeds. In order to determine the Sagnac phase from the output signal of a fiber optic annular interferometer, without the need for costly circuits for regulating a phase modulator that acts on the interference light and for regulating the intensity of the light, the Sagnac-phase phi is deduced from the amplitudes (A DOLLAR (g)n-1, A nu , A nu +1) of three spectral lines of the interference light that is emitted by the interferometer.
