MAGNETIC SENSOR MODULE AND METHOD FOR DETERMINING OPERATION CONDITION OF MAGNETIC SENSOR MODULE

Abstract: a magnetometer module includes a cell, a pump laser light source, a photodiode configured to detect an intensity of pump light, a probe laser light source, a photodiode element configured to detect an intensity of probe light, a differential amplifier configured to generate a magnetism detection signal based on the probe light that has passed through the cell, and a control circuit configured to perform at least one of first determination processing of determining a driving condition of the light source based on the intensity of the pump light detected by the photodiode while controlling the light source and performing wavelength sweep on the pump light and second determination processing of determining a driving condition of the light source based on the intensity of the probe light detected by the photodiode element while controlling the light source and performing wavelength sweep on the probe light.
