Technical Principle and Test Research of a Prototype Quantum Magnetometer

A quantum magnetometer is an instrument that utilizes the quantum effect for high-precision magnetic field measurement. In this paper, a prototype quantum magnetometer is analyzed by innovative use of differential optical path, frequency tracking, and vector magnetometry. And based on analyzing its original departure, its sensitivity and broadband data situation is derived after testing, showing that the current system magnetic sampling rate is 15 Hz and the measured broadband is about 5 Hz. The results show that the Alternating Current (AC) vector magnetometry function, Direct Current (DC) vector magnetometry function and sensitivity calculation function are normal.
