Magneto-optic Current Sensor Based on Total Reflections in a Quadrangular Bulk Glass
摘要
Abstract
A novel optical device of a bulk glass Faraday current sensor is presented,which has a accuracy of 0. 5 in the current region of 1 000- 8 000 A and over a temperature range from-30℃ to + 40℃. The new sensing device can compensate the phase difference between p and s components of the incident light caused by total internal reflections in a glass. The self-correction, auto-correlation and auto-amplification techniques are used in the signal treatment with the help of a computer.
