中文摘要:
      铯光泵原子磁强计利用极化铯原子自旋拉莫尔相干进动探测和测量磁场,具有精度高、响应快等特点。围绕铯光泵原子磁强计的技术特点,重点介绍了其工作原理及研制工作,实现了一款铯光泵原子磁强计整机。测试结果表明,该款磁强计磁场测量范围为20000~100000nT,峰峰噪声值为00017nT,能满足磁异常探测对高精度磁强计的需求。
English Summary:
      The optically pumped cesium atomic magnetometer detects and measures magnetic fields by using the Larmor coherent precession of polarized cesium atomic spins, which features high sensitivity, fast responseDue to its technical features, the principle of operation and the development work is mainly introduced, then a cesium atomic magnetometer prototype is realizedThe test results showed that its operating range is from 20000nT to 100000nT, and noise of peak to peak is 00017nT, which can be applied to a high performance magnetometer, and meet the demand for magnetic anomaly detection.
