Abstract: A method and apparatus for determining a rate of rotation uses a fiber-optic gyro which has a 3.times.3-coupler. A first channel of the coupler is optically connected on one side with a light source and on the other side with a first photo element; and the two other channels are optically connected on one side with a fiber coil and on the other side with a second and third photo element respectively. A depolarizer is arranged at least between the light source and the 3.times.3-coupler or at one end of the fiber coil; alternatively, the fiber coil has a polarization-maintaining fiber. An electronic signal processing system is used to determine a temperature-related value, independent of the rate of rotation, for damping of the fiber coil and of the 3.times.3-coupler, based on the signals of the three photo elements and from temperature-dependent coefficients determined by calibration.
