RESEARCH CASE ON THE DESIGN OF POLARIZED LIGHT RENDERER AND TEACHING PRACTICE OF PHYSICAL OPTICS

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.
