摘　　要：高灵敏度磁场测量技术在空间探测、军事反潜、生物磁场测量和地质探测等方面发挥着重要作用。为了提高磁力仪灵敏度同时减小磁力仪体积,本文设计了一种全光结构的原子磁场测量方案。首先基于探测光偏振调制技术,设计了原子磁力仪的总体方案。在此基础上,重点研究了小型化磁传感Rb原子气室、无磁电加热、激光器稳频和偏振调制等关键技术。目前已完成实验室测磁原理的验证。The magnetometers with the high sensitivity have played an important role in the space exploration,the anti-submarine,the measurement of the biological magnetic field and the geological exploration.A kind of all-optical structure atomic magnetometer is introduced in the paper in order to improve the sensitivity and decrease the size.Firstly,the general scheme of the atomic magnetometer based on the polarization-modulated light is designed.Then the key technologies are researched,such as the Rb atomic cell,non-magnetic heating,laser frequency locking and polarization modulation.Up till now,the magnetic field measurement prototype has been implemented.
