PCT No. PCT/DE96/02248 Sec. 371 Date Jun. 2, 1998 Sec. 102(e) Date Jun. 2, 1998 PCT Filed Nov. 22, 1996 PCT Pub. No. WO97/21108 PCT Pub. Date Jun. 12, 1997In mutually opposite directions, two light signals traverse an optical series circuit including a first multi-mode fiber, a first polarizer, a Faraday sensor device, a second polarizer and a second multi-mode fiber. An intensity-normalized measuring signal is derived with the aid of direct signal components from light intensities of the two light signals after traversal of the series circuit.
