ABSTRACT:
An arrangement for the magneto-optical measurement of currents with a linearly polarized light beam in which the measuring path contains an analyzer with two orthogonal pass directions, over which the partial beams are conducted, has a light deflector which directs one partial beam alternatingly at a high frequency to a detector which is arranged in the other partial beam so that the detector receives alternatingly the measurement signal with the noise component and the noise component only.
