<p>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 ζ is deduced from the amplitudes (A$(g)n-1, Aξ, Aξ+1) of three spectral lines of the interference light that is emitted by the interferometer.</p> |
