The invention relates to a miniature helium optical pump magnetometer applicable to a small-sized aircraft, comprising a mainframe, a helium optical pump probe A and a helium optical pump probe B, wherein a motherboard, a helium optical pump magnetometer circuit, a GPS (Global Positioning System) board and a switching power supply module are arranged in the mainframe; the motherboard is respectively connected with the helium optical pump magnetometer circuit, the GPS board, a serial port A, a serial port B and a serial port C; the helium optical pump magnetometer circuit is connected with the helium optical pump probe A by an interface of the helium optical pump probe A and connected with the helium optical pump probe B by an interface of the helium optical pump probe B; an input end of the switching power supply module is connected with a power supply input interface by a power supply switch; and an output end of the switching power supply module is respectively connected with the motherboard, the GPS board and the helium optical pump magnetometer circuit. The miniature helium optical pump magnetometer provided by the invention has the advantages of small volume, light weight, low power consumption, and capabilities of automatically collecting multiple data in an unmanned way and replacing an optical pumping magnetometer, a magnetic compensating instrument and an aviation comprehensive data collecting system in the traditional aeromagnetic survey system.

Description

technical field [0001] The technical field of airborne magnetic survey of the present invention is mainly a mini helium optical pump magnetometer suitable for small aircraft. Background technique [0002] In the field of mineral and petroleum exploration, optically pumped magnetometers are widely used for airborne magnetic surveys. In the prior art, large-scale fixed-wing aircraft such as Y-12 are used for aerial surveys when conducting airborne magnetic surveys. Y-12 aircraft are strictly controlled by civil aviation and military, and flight approval is required, and the procedures are cumbersome and strict. In addition, pilots need to be trained in specialized aviation driving schools for many years, and the cost of using such aircraft for aeromagnetic surveys is also relatively high. With the continuous development of UAV technology, as an unmanned aerial platform in the aviation aircraft series, it has great potential in the fields of military reconnaissance, aerial pho...
