MAGNETOMETER

摘要

The present invention may be used to increase the sensitivity and stability of a magnetometer while performing a three-component recording. The magnetometer of the present invention includes a sensitive member that comprises a YIG-film maintained at a mono-domain state as well as two orthogonal coils, wherein the magnetisation direction of the mono-domain runs about a circle. The present invention uses a device for generating a rotating magnetic field, wherein said device consists of a dual-channel harmonic vibration generator having a pi /2 phase-shift between said two channels. The present invention also uses a device for processing according to a zero method the response signal from the sensitive member when measuring the magnetic field, wherein said device comprises a system for establishing a feedback link and is connected to a user's interface.
