ABSTRACT:
A measurement head for a magnetic field gradient vector measuring apparatus, comprising essentially a laser diode emitting two light beams aligned along the same axis. Two magnetic field measuring cells are placed in the paths of these light beams. Each cell comprises a wafer coated with a layer of a magnetic material forming a waveguide. The purpose of each cell is to measure the Faraday effect on the polarization of the magnetic field by using a zero method. A difference circuit then calculates the difference between the commands given to each cell so as to find the value of the magnetic field gradient.
