物理与工程

物理光学课程致力于通过教学主体转换,推进以学为中心的教学模式。本文设计并实现了基于路径追踪和光线追踪算法的基础线偏振光学场景渲染器,对场景中的偏振光传播和交互进行高精度模拟,生成动态可视化的偏振光场效果。研究以实验与渲染“虚实结合”的方式,验证了渲染器对于偏振光菲涅耳反射在不同入射角下的仿真准确性,有效提升学生对偏振光学理论的理解和应用能力。该研究为物理光学和光学原理课程的教学实验提供了具备量化验证功能的新工具及可视化支持。

The course of physical optics is committed to promoting a learning-centered teaching model through the transformation of teaching subjects. This paper designs and implements a basic linear polarization optical scene renderer based on path tracing and ray tracing algorithms, which carries out high-precision simulation of the propagation and interaction of polarized light in the scene and generates dynamic visual effects of the polarized light field. The study verifies the simulation accuracy of the renderer for the Fresnel reflection of polarized light at different angles of incidence by means of “virtual-real combination” of experiments and rendering, effectively improving students' understanding and application ability of polarization optics theory. This research provides new tools with quantitative verification functions and visual support for the teaching experiments of Physical Optics and Optical Principles courses, which is helpful to promote the digital transformation of optical teaching.
