Title: Method and device for measuring a magnetic field

Abstract: According to the present invention, in a method, two polarized light signals are sent in opposite directions through a sensor exhibiting the Faraday effect. To minimize the influence of light portions that are reflected on light paths, one light signal is transmitted on one wavelength, and the other is transmitted on another wavelength. The present invention is applicable in particularly vibration-compensated magneto-optical current converters for purposes of avoiding the influence of back-reflections on the measuring signal.
