Abstract

Abstract Translated from French L'invention concerne une tête de mesure de champ magnétique comprenant, intégrés sur un même substrat (1) : une source lumineuse (E1) ; un guide de lumière (G1) insensible au champ magnétique ; une couche de matériau magnétique (F1), permettant lorsqu'elle est plongée dans un champ magnétique à mesurer, de faire tourner le plan de polarisation de la lumière venant de la source ; et des moyens de mesure de rotation du plan de polarisation de la lumière. L'invention est applicable aux magnétomètres. The invention relates to a magnetic field measuring head comprising, integrated on the same substrate (1): a light source (E1); a light guide (G1) insensitive to the magnetic field; a layer of magnetic material (F1), allowing when immersed in a magnetic field to be measured, to rotate the plane of polarization of the light coming from the source; and means for measuring the rotation of the plane of polarization of the light. The invention is applicable to magnetometers.
