摘要: 随着海洋环境探测工作的发展,海域磁测对磁力仪在微小型化、高精度方面提出了新的需求.在介绍了几个常见的弱磁场测量仪器后,重点分析了一种基于双光场量子干涉效应的磁力仪.根据在磁场中光与原子相互作用的物理机制,阐析了利用量子干涉效应进行高精度磁场测量的基本原理.在此基础上,分析了在芯片上实现量子干涉磁力仪的可能性,详细讨论了芯片量子干涉磁力仪的一种设计方案,并给出了芯片量子干涉磁力仪的性能预期以及其在海洋磁测领域的应用前景.

Abstract: With the development of the marine environment survey, marine magnetic survey demands magnetometers with micro-size, high-precision magnetometer. The several common weak magnetic field measurement instruments were described, and an analysis of a magnetometer based on dual light-field quantum interference effects was focused on. Based on the physical mechanism of the interaction between light and atoms in a magnetic field, the interpretation of the basic principles of quantum interference effects for high-precision measurement of magnetic field was given. On this basis, the possibility of realizing a chip-scale magnetometer based on quantum interference effects was analyzed. After that, design of a chip-scale quantum interference magnetometer was discussed in detail, and the performance expectations and prospects for its application in marine magnetic survey was given.
