Abstract

The invention provides a radio frequency thin film for an optically pumped 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, and a metal material is etched on the other surface of the substrate One surface is coated with an adhesive, the metal material is etched at the end to weld lead-out wires, and the current flows in the adjacent etched metal material lines in the same direction. The radio frequency thin film of the present invention is applied to the outer surface of the atomic gas chamber, which greatly reduces the occupied space of the radio frequency coil, and the size of the thin film is flexible and adjustable, which is convenient for installation and disassembly; it is used in the magnetometer, which is beneficial to the miniaturization of the magnetometer probe ; and based on the controllability of the etching circuit, it can meet different requirements for magnetic field distribution.

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...
