method for measuring the phase difference of two nichtreziproken electromagnetic waves in a ringinterferometer and device for implementation of the procedure

摘要

The invention relates to the measurement of a phase shift not reciprocal in a ring interferometer. / p & & p & it relates to an interferometric device has a ring comprising means of optical phase shift acting on the radiation passing through the ring 2, these means comprising an oscillator issuing a periodic voltage of frequency 12t, or t is the time taken by a radiation to pass through the ring and a list of the sawtooth, the frequency of resonance is slaved to the phase shift not reciprocal. / p & & p & application in particular for the measurement of speeds of rotation and the measured currents.
