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. WebWe have demonstrated phase modulation of rotating linearly polarized light by current-induced Faraday rotation in a single mode optical fiber and used the technique to measure the current in ZT-40M, a Reversed-Field Pinch. We have also demonstrated the practicality of using twisted sensing fiber to overcome the problems associated with linear birefringence.
