Focusing on the measurement and calibration of high-sensitivity magnetic sensors, a study on geomagnetic noise compensation based on cesium optical-pumping magnetometer was carried out. On the basis of the atomic spectrum lamp cesium optical-pumping magnetometer, the study replaced atomic spectrum lamp with laser as the light source of the cesium optical-pumping magnetometer, designed the laser optical-pumping magnetometer, and applied it to the geomagnetic noise compensation system. The magnetic field compensation capability of the optical-pumping magnetometers geomagnetic noise compensation system was analyzed through experiments on the two types of the optical-pumping magnetometers. Experimental results show that the geomagnetic noise compensation system based on the above two types of cesium optical-pumping magnetometers both can reproduce magnetic field with a noise power spectral density better than 0.5 pT/Hz1/2 @1 Hz and a noise peak-to-peak lower than 10.8 pT (10 Hz sampling rate), and the laser optical-pumping magnetometer has better compensation effect under large magnetic field. The results provide important reference for designing geomagnetic noise compensation systems for magnetic sensor metrology and calibration.
