[0025] Such as figure 1 As shown, the present invention proposes an atomic transverse relaxation time automatic detection system, which is characterized by including: a laser generation module, a polarization modulation module, an atomic gas cell, a signal detection module, and an upper computer;
[0026] The upper computer controls the laser generating module to generate laser light, and the upper computer controls the polarization modulation module to modulate the polarization state of the laser so that the polarization state changes according to a specific time sequence. Different polarization states play the role of pump light and probe light respectively. The light polarizes the atoms, and the probe light is used to detect the polarization intensity of the atoms. At the same time, the upper computer collects the light intensity of the probe light transmitted from the atomic gas cell through the signal detection module; the upper computer controls the polarization modulation mo...
