摘要
弱磁测量技术在许多诸如生物医学、资源勘测、军事工程和空间探测等重要领域中占有不可或缺的地位,在很大程度上也代表了国家磁测技术的发展水平。当前国内外弱磁测量主要用到质子磁力仪、光泵磁力仪、原子磁力仪、磁通门、SQUID、光纤磁力仪和磁电阻传感器,按照测量磁场的类型将其分为标量和矢量型,通过其基本原理、特性、研究和应用现状的分析,对其发展方向和应用前景进行了综述,为后续的理论研究和工程实践提供参考。
The technology of detecting weak magnetic field plays an indispensable role in lots of momentous areas,such as bio-medicine,resources exploration,military and aerospace engineering. To a great extent,it also represents the level of detecting magnetic field of a country. The major sensors of detecting weak magnetic field currently are Proton Magnetometer,Optical pumping,Atomic Magnetometer,Fluxgate,SQUID,Fiber-optic and Magneto resistance,which are used at home and abroad,and can be divided into scalar type and vector type in measuring magnetic field,according to analyzing their principle,property and state of technology and application,future research orientation and application foreground are all reviewed in this thesis,which will provide the reference for further theoretical research and engineering practice.
