Influence of Polarization State on InterferenceFringe Contrast
摘要
基于迈克耳孙干涉仪原理研究不同偏振态光的两偏振分量大小对干涉条纹对比度的影响。同时,为快速计算条纹图像的对比度,提出一种基于Matlab的干涉条纹对比度计算方法。最后通过分析实验数据获取不同偏振态光的两偏振分量和干涉条纹对比度间的关系。该研究成果可运用于干涉仪器或干涉实验中,通过在光源处引入偏振调制来获得对比度高的干涉条纹图像,以提高测量精度。
Abstract
The effects of two polarization components of different polarization states on the interference fringe contrast are investigated based on the principle of Michelson interferometer. Simultaneously, a Matlab-based interference fringe contrast calculation method is used to quickly evaluate the fringe image contrast. Finally, the relationship between the polarization components of different polarization states and the interference fringe contrast can be obtained by analyzing the experimental data. The results demonstrate that this research can be applied to either interference instruments or interference experiments. Introducing polarization modulation at the light source to obtain high-contrast interference fringe images will improve the measurement accuracy.
