    • 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).

    • After passing through a Faraday sensor device (3), linearly polarised measuring light (L) is broken down in an analyser (7) into two diffently polarised partial light signals (L1, L2). The intensity of the corresponding electric signals (I1, I2) is normal by dividing their alternating signal component by their direct signal component. A measuring signal S = (2*S1*S2)/((S2-S1)+K*(S1+S2)) is derived from the two normalised intensity signals, in which cos(2 theta +2 eta )=-2/(3K) and sin(2 theta -2 eta )=1 stand for a correction factor K, an injection angle eta between the polarisation plane of the injected measurement light (L) and a proper axis of the linear double-fraction in the sensor device (3) and a decoupling angle theta between this proper axis and a natural axis of the analyser (7).
