Abstract

The invention provides a radio frequency film for an optical pump magnetometer, comprising: an electromagnetic layer, the electromagnetic layer comprising a flexible insulating substrate, wherein: a metal material is etched on one surface of the substrate, the other surface of the substrate is coated with an additive, an outgoing line is welded to the etching terminal of the metal material, and the flow directions of current in adjacent metal material lines formed by etching are identical. The radio frequency film applied to the outer surface of an atomic gas chamber greatly reduces the spaceoccupied by a radio frequency coil; the size of the film is flexible and adjustable, which is convenient for assembly and disassembly; the radio frequency film for a magnetometer facilitates miniaturization of a magnetometer probe; and based on the controllability of the etched lines, different needs for magnetic field distribution can be met.

Description

technical field [0001] Embodiments of the present invention relate to magnetometers and components thereof, in particular to a radio frequency thin film for an optically pumped magnetometer. Background technique [0002] In recent years, magnetic field measurement methods have emerged continuously. Optical pump magnetometer is a device based on Zeeman splitting and using optical pump and magnetic resonance technology for magnetic field measurement. It is widely used in geological structure survey, mineral resource detection, biomedicine, Geomagnetic navigation and other fields. Among them, the atomic gas chamber is an important part of many quantum measuring instruments. In a magnetometer, radio frequency coils are used to provide a magnetic field in a specific direction to the atoms within the atomic gas chamber, causing the atoms to undergo magnetic resonance. [0003] The radio frequency coil is an important component of the magnetometer, and the alternating magnetic fi...
