Ultra-sensitive permeability detecting apparatus using atomic ?? susceptometer and using method thereof

摘要

This invention is based on atomic magnetometers AC permeability measurement techniques, and more particularly to optical pumping atom by a magnetometer that measures the magnetic field sensitivity is excellent, blood by measuring the change of the alternating magnetic permeability measured by the target sample, second trace sample (e.g., biological molecules) to detect the possible measurement apparatus and method for use thereof relates. The present invention is an alkali metal atom is affected by the magnetic field due to the sample containing the cells (110); Cell light source to the magnetization of the alkali metal atoms 110, 120; Bias magnetic field for adjusting the measured resonant frequency of the alkali metal atom (Bo) applying a bias magnetic field applying unit 130; atom magnetic means including a (100); A plurality of alternating magnetic field having a predetermined frequency for exciting the sample with magnetic (Bs ₁ , Bs ₂ ) in this magnetic field (Bs) configured to be applied to the sample This magnetic field applying means (200); And means for detecting this magnetic field magnetically by measuring the change of the magnetic polarization of the alkali metal atom affected by a magnetic field (B) by the excited sample detects a permeability change in the sample with (Bs) (300); including which is characterized in that.
