Two light signals pass through a series connection of a first multimode optical fiber, a first polarizer, a Faraday sensor device, a second polarizer and a second multi- mode optical fiber in opposite directions. The polarization axes of the two polarizers are set at a polarizer angle .eta. or .theta. to the natural axis of the linear birefringence in the sensor device with cos(2.eta. + 2.theta.) = -2/3. The measuring signal is derived as the quotient of two linear functions of the light intensities of the two light signals after passing through the series connection.
Deux signaux lumineux (L1', L1, L2', L2) parcourent un montage en série comprenant un premier guide d'ondes multimode (4), un premier polariseur (5), un dispositif de détection de Faraday (3), un second polariseur (6) et un second guide d'ondes multimode (7), en sens opposé l'un par rapport à l'autre. Les axes de polarisation des deux polariseurs (5, 6) sont ajustés à l'aide de cos(2 eta +2 theta )=-2/3, en formant à chaque fois un angle de polarisation eta et theta par rapport à l'axe de la biréfringence linéaire, dans le dispositif de détection (3). Le signal de mesure (M) obtenu est le quotient de deux fonctions linéaires des intensités lumineuses (1, I2) des deux signaux lumineux (L1, L2) après qu'ils aient parcouru le montage en série.
