Over the years, significant effort has been directed towards the development of quantitative micro-magnetic structure mapping via magneto-optical imaging (MOI). In this regard, several different approaches have been proposed to cope with different experimental environments. However, there are still open questions in the process of quantification with respect to non-uniform illumination, the resolution of positive and negative magnetic fields, camera parameters, and polarized light path settings. In this work, we combine a new processing method with three-rotation angle calibration to substantially optimize the calculation results, leading to a more versatile calibration method. Moreover, we also investigate the effects of the camera parameter setting, noise, and pre-rotation angle on the calculation results. This facilitates the flexible adjustment of the experimental parameters to allow for adaptation to different test environments.

一种非均匀光照下定量磁光测量的新方法

多年来，人们已经通过磁光成像（MOI）致力于定量微磁结构图的开发。在这方面，已经提出了几种不同的方法来应对不同的实验环境。但是，在量化过程中，关于不均匀照明，正负磁场的分辨率，相机参数和偏振光路径设置，仍然存在未解决的问题。在这项工作中，我们将一种新的处理方法与三转角校准相结合，从而大大优化了计算结果，从而提供了一种更加通用的校准方法。此外，我们还研究了相机参数设置，噪声和预旋转角度对计算结果的影响。
