ABSTRACT:
A method for temperature calibration of an optical magnetic field measurement array and a measurement array calibrated by the method include an optical series circuit having a first optical transmission path, a first polarizer, a Faraday sensor device, a second polarizer, and a second optical transmission path. The optical series circuit is temperature-calibrated by adjusting the polarizer angles of the two polarizers in a special way. The calibration method functions even if the intrinsic axis of the linear double refraction in the sensor device is unknown.
