Abstract

The density detection and orientation identification of the magnetic field are crucial across various industrial sectors and scientific researches. In this work, we detected both the magnetic field density and its orientation by utilizing the polarized light passing through a TGG crystal to generate the multiple self-mixing interference with the Faraday effect. The spectral lines of the multiple self-mixing interference were experimentally obtained in the magnetic field ranging from -80.31 mT to 79.44 mT and the spectral lines exhibited opposite trends on the condition of an inverted magnetic field. The results were analyzed based on the decay coefficients of the spectral lines obtained via fitting, and they exhibited an upward or a downward trend when the orientation of the magnetic field was inverted.

基于多重自混合干扰的定向磁传感

磁场的密度检测和方向识别在各个工业部门和科学研究中都是至关重要的。本研究利用偏振光穿过TGG晶体产生法拉第效应的多重自混合干涉来检测磁场密度和磁场方向。在-80.31 ~ 79.44 mT的磁场范围内，实验得到了多重自混合干涉的谱线，在反向磁场条件下，谱线呈现相反的趋势。对拟合得到的谱线衰减系数进行了分析，结果表明，当磁场方向反转时，谱线衰减系数呈现上升或下降的趋势。

期刊介绍： Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
