Abstract

La présente invention peut être utilisée pour mesurer les propriétés magnétiques des divers objets biologiques et physiques et aussi pour enregistrer de différents marqueurs magnétiques et pour mesurer des champs magnétiques. L'échantillon à mesurer se trouve dans la zone d'action du champs magnétique formé par le bloc d'inductivité qui est branché aux entrées des générateurs des signaux d'excitation et de modulation. A l'entrée du bloc d'inductivité est branché un filtre qui est réglé à la transmission du signal de la fréquence désignée se représentant sous forme d'une combinaison linéaire des fréquences des signaux d'excitation et de modulation. Pour mesurer le champs magnétique on enregistre les variations de la susceptibilité magnétique d'un élément sensible se trouvant sous l'influence d'un champs extérieur. L'invention permet d'augmenter le rapport signal/bruit et, en conséquence, d'améliorer l'exactitude de mesure, d'accroître la sensibilité de l'instrument de mesure et la fidélité des données obtenues. Cette invention diminue les frais par la réduction du nombre et des gabarits de l'équipement nécessaire, améliore la flexibilité fonctionnelle du dispositif et élargis son diapason d'application.
