ODMR型磁力仪灵敏度的角相关特性分析
Analysis of Angular Correlation Characteristics of ODMR Magnetometer Sensitivity
摘要
Abstract
The angular correlation characteristics of the sensitivity of the optically detected magnetic resonance(ODMR)magnetometers determine the optimal operating angle range of the ODMR magnetometer.The mathematical expression of the detecting signals of ODMR magnetometers under different polarized light,radio frequency electromagnetic field,and measured magnetic field configurations is de-rived.Based on this,an in-depth analysis is conducted on the angle dependence of the detecting sensitivity of MX magnetometers based on measuring horizontal components and MZ magnetometers based on measuring vertical components.The results indicate that there is a significant difference in the angular correlation characteristics of sensitivity between MX and MZ magnetometers under Brf∥k and Brf⊥k conditions.Based on this,the optimal installation angle for magnetic field measurement of ODMR magnetometers with different configu-rations is obtained.关键词
