Abstract

In this paper, some parameters are studied for the performance improvement of a bulk optical magnetic-field sensor. The performance of optical magnetic-field sensor is influenced by optical intensity change and wavelength change of light source, and phase shift so called optical bias mismatch. A magnetic field measuring system based on optical Faraday sensor is implemented and tested in the current range from 10 ampere to 200 ampere. The test result shows implemented system has goof linearity.
