Polarised measuring light (L) is coupled into a sensor device (3) and, after passing through the sensor device (3), divided into two differently linearly polarised partial light signals (L1, L2) in an analyser (7). The intensity of the corresponding electric intensity signals (I1, I2) is standardised by the division of their alternating signal component by their direct signal component. From the two standardised intensity signals S1 and S2 is derived a temperature-compensated measurement signal M in accordance with the two equations S1 = f1(T)*M and S2 = f2(T)*M in which f1(T) and f2(T) are predetermined, especially linear, squared or exponential fit functions of the temperature T. The measurement signal M = A*S1+B*S2 is obtained in particular with linear fit functions f1(T) and f2(T).
La lumière de mesure (L) polarisée est injectée dans un dispositif de détection (3) qu'elle traverse avant d'être décomposée dans un analyseur (7) en deux signaux lumineux partiels (L1, L2) polarisés linéairement de manière différente. L'intensité des signaux correspondants (I1, I2) est ensuite normalisée par division de chacune de leurs composantes de courant alternatif par chacune de leurs composantes de courant continu. Un signal de mesure M à compensation thermique est dérivé des deux signaux S1 et S2 à intensité normalisée, d'après les deux équations S1 = f1(T)*M et S2 = f2(T)*M, f1(T) et f2(T) étant des fonctions d'ajustement données, notamment linéaires, quadratiques ou exponentielles de la température T. Les fonctions d'ajustement linéaires f1(T) et f2(T) permettent notamment d'obtenir le signal de mesure M = A*S1+B*S2.
