Abstract

The invention provides an optical pump magnetometer gradient tolerance measuring device. The optical pump magnetometer gradient tolerance measuring device mainly comprises a horizontal base, a gradient generating coil, a horizontal connecting rod, bubble levels, a connecting rod leveling device, an optical pump probe mounting clamp, a laser range finder, a precise current source and a measuring and control module, wherein the measuring and control module calculates the magnitude of currents which need to be output to generate a specific magnetic gradient according to preset parameters such as the probe position, probe size, coil turn number and coil radius and controls the precise current source through a USB interface to output specific currents to the gradient generating coil; the gradient generating coil is mounted on the horizontal base, the position of the gradient generating coil is adjusted through the bubble level A, and the gradient generating coil generates the magnetic gradient in a surrounding space; the optical pump probe mounting clamp is arranged on the horizontal connecting rod, and the horizontal connecting rod is regulated through the bubble level A, the bubble level and the connecting rod leveling device to be parallel with the axis of the gradient generating coil.

Description

technical field [0001] The invention relates to a technical indicator measuring device for an optical pump magnetometer, in particular to a gradient tolerance measuring device for an optical pump magnetometer. Background technique [0002] The optically pumped magnetometer is based on the Zeeman energy level splitting of the working substance atoms in the external magnetic field. It has been successfully developed in combination with the optical pumping effect and the magnetic resonance phenomenon. It has been widely used in ground geophysical prospecting, aviation geophysical prospecting, aviation anti-submarine Magnetic material detection and other fields. [0003] The magnitude of the magnetic resonance signal of the optical pump magnetometer is affected by the gradient of the external magnetic field. The larger the gradient of the external magnetic field, the smaller the resonance signal, which will cause the performance of the magnetometer to decline or even malfunction...
