Abstract: The present invention relates to a fiber-optic gyrometer comprising a Sagnac interferometer using two light waves (S1, S2) propagating in opposite directions in a ring waveguide (2), comprising a photodetector (4) which delivers an electrical signal Ud representing the light intensity of the interference between the two waves, and means (5) for optically phase-shifting the waves controlled by a square-wave modulation signal Um suitable for controlling an optical phase variation at a frequency FO substantially equal to ½.t0, where to is the propagation time of a wave through the guide (2).

Abstract: The method according to the invention for preventing bias errors as a result of synchronous interference in fiber-optic gyroscopes (FOGs) provides for an additional signal &phgr;E, which is periodical at the sampling clock rate and corresponds, for example, to a synchronous interference signal input to be added in the form of additional modulation to the modulation signal for a phase modulator within an MIOC. The demodulated detector signal from the FOG is preferably then correlated with the additional modulation, that is to say which is multiplied by the additional modulation and is added to it. The added-up signal, which is dependent on the error matching, controls a VCO (12) which readjusts the operating frequency of the FOG until the correlation tends to zero. The method can be used not only for phase ramp modulation but also for FOGs which operates using a random phase modulation method.

The probe head directs both the light in the first mode and the returned light from the sample in the second mode through a common optical path to a detection module.

Abstract: Embodiments in accordance with the invention provide an optical spectrum analyzer. The optical spectrum analyzer includes a receiver for receiving an optical local oscillator signal and an unknown optical signal. The receiver outputs three or more phase-diverse heterodyne signals.

The first and second phase quadrature signals are coupled to a complex signal generator. The complex signal generator produces a complex signal having a positive and negative image. A measurement processing unit determines the phase of the unknown optical signal from the relative difference of the phase of the positive and negative image of the complex signal.
