摘要

近年来，利用碱金属原子的自旋极化来测量磁场的光泵磁力仪（OPMs）引起了人们的广泛关注。然而，为了利用opm实现高灵敏度的生物磁场测量，必须降低环境磁噪声和系统噪声。在本研究中，我们研究了使用主成分分析、独立成分分析和经验模态分解对OPM信号进行降噪的有效性。

Studies on Noise Reduction of Optically Pumped Magnetometers by Digital Signal Processing

Recently, optically pumped magnetometers (OPMs), which use the spin polarization of alkali metal atoms to measure magnetic fields, have attracted much attention. However, in order to realize high-sensitivity biomagnetic field measurements using OPMs, it is necessary to reduce environmental magnetic noise and system noise. In this study, we investigate the effectiveness of the noise reduction of OPM signals when principal component analysis, independent component analysis, and empirical mode decomposition are used for signal processing.
