微弱磁场测量仪研究近况

摘要

Numerous things come true by measuring weak magnetic field,such as disease diagnoses,mineral and oil detecting,military aim finding,industry non-destructive measuring and intellective navigation.The basic principle,state of technology and application of four kinds of magnetometers are introduced in this paper.They are resonance magnetometer,optic atomic magnetometer,SQUID and magneto-electric effect magnetometer which are very useful in measuring weak magnetic field.At the meantime,the characters of the four kinds of magnetometers,future research orientation and application foreground are all reviewed in this thesis.%疾病的诊断、矿藏石油的探测、军事目标的探测、工业无损检测、智能导航等都可以通过对磁场信号的探测实现.介绍了共振式磁强计、全光学原子磁强计、超导量子干涉(SQUID)磁强计、磁电效应磁强计四大类可用于微弱磁场测量的磁强计的基本原理、研究及应用现状,同时对各类磁强计的特点、未来研究方向及应用前景进行了综述.
