偏振光实验是大学物理实验的重要组成部分,但其核心概念较为抽象,传统教学手段难以动态、直观地展示其内在规律。基于Matlab开发了用于偏振光实验教学的交互式数字资源,包含偏振状态、马吕斯定律和布儒斯特定律三个部分,动态展示了光的偏振状态变化、马吕斯定律中出射光强的变化和布儒斯特定律中布儒斯特角及反射率的变化,有助于学生直观理解光的偏振状态、马吕斯定律和布儒斯特定律。此外,学生可通过自主调节参数深入观察现象、验证物理规律,从而有效弥补传统实验的局限,深化对偏振光原理的理解,达到辅助教学与提升学习效率的目的。
Abstract：Polarized-light experiments are an important component of college physics laboratory teaching. However, their core concepts are relatively abstract, and traditional teaching methods often fail to present the underlying physical mechanisms in a dynamic and intuitive manner. In this study, a MATLAB-based interactive digital resource was developed for the teaching of polarized-light experiments. The resource consists of three modules: polarization states, Malus' law, and Brewster's law. It dynamically visualizes the evolution of light polarization states, the variation of transmitted light intensity in Malus' law, and the changes in Brewster angle and reflectance in Brewster's law. These visualizations help students intuitively understand polarization states, Malus' law, and Brewster's law. In addition, students can independently adjust relevant parameters to observe physical phenomena and verify theoretical laws, thereby overcoming some limitations of traditional experiments and deepening their understanding of polarized-light principles. The proposed resource can serve as an effective auxiliary teaching tool and help improve students' learning efficiency.
