Abstract:
An optical magnetic field sensor probe for detecting a magnetic field, comprising:a case,an input optical fiber for inputting light into the optical magnetic field sensor probe,a first lens,a polarizer,a first mirror for reflecting light from the first lens to the polarizer,a magneto-optical device,an analyzer,a second lens,a second mirror for reflecting light from the analyzer to the second lens, andan output optical fiber for emitting light from the optical magnetic field sensor probe,wherein the input optical fiber, the first lens, the first mirror, the magneto-optical device, the second mirror, the second lens, and the output optical fiber are arranged in order to form a pi-shaped optical system within the case, and the first mirror and the second mirror are structured by evaporation onto interior walls of the case.
