PROCESS AND DEVICE FOR MODULATING THE PHASE OF THE WAVES TRAVELING IN A RING INTERFEROMETER ABSTRACT OF THE DISCLOSURE Procedure consisting in inserting along the ring of a ring interfero- meter at least one reciprocal-effect phase modulator. The .PHI.(t) function, representing the modulation of the phase of the two waves traveling in opposite directions in the ring of the interferometer, is a periodic function confirming the relationship .PHI.(t) = .PHI.(t + 2?), where ? is the time which electromagnetic waves take to travel round the ring. The effect of this modulation is to shift the measuring point on the curve representing the optical power depending on the variation of the phase difference .DELTA.? between the two waves and to obtain a maximum sensitivity of the measurement about the point (.DELTA.?) = 0 by making the power component detected, representing the magnitude to be measured, proportional to sin (.DELTA.?). A control signal generator supplies simultaneously these signals to the modulator and to a synchronous detector.
