摘要：
A sensor far alternating electric current measurement based on optical Faraday rotation with a specially designed twisted fibre is reported. A signal processing technique is demonstrated to stabilize the sensor output against temperature variations and polarization fluctuations in the fibre. The current sensitivity measured experimentally is 1.16 x 10(-6) rad A(-1), in good agreement with the theoretical value.
