WebApr 1, 2014 · The Faraday rotation of the plane of polarised light is linearly proportional to the current-induced magnetic field and the distance the light has travelled. The change in the polarisation azimuth is translated into a power modulation of the optical signal, and thus provides a measure of the current. WebJun 9, 2011 · Abstract: Fiber optical current sensor (FOCS) is a technique considered to be compatible with the ITER nuclear environment. FOCS principle is based on the magneto-optic Faraday effect that produces non-reciprocal circular birefringence when a magnetic field is applied in the propagation direction of the light beam.
