摘　　要：拉曼光谱可以提供细胞分子水平信息,是分子机制研究中强有力的工具,因此,运用光学新技术从单细胞分子水平上提取动植物信息的新方法已成为生命科学等领域中相当重要的方法。实际应用中,为光谱的进一步分析提供真实的光谱数据尤为重要,因此拉曼光谱系统的稳定性就显得尤为重要。本文将马吕斯定律理论应用于拉曼光谱系统,利用偏振片控制光功率的稳定性,旨在提高系统的稳定性,获取更加真实、准确的光谱信息。Raman spectroscopy can provide information on the molecular level of cells,which is a powerful tool in the study of molecular mechanism. Therefore,the new method of extracting animal and plant information from single cell molecular level by optical technology has become a very important method in the field of life science.In practical application,it is important to provide real spectral data for further analysis of the spectrum,so the stability of the Raman spectroscopy system is particularly important. In this paper,the Marius＇ s law is applied to the Raman spectroscopy system. The stabiliW of the optical power is controlled by the polarizer. Our aim is to improve the stability of the system and obtain more realistic and accurate spectral information.
