Introduction

Geometric optics is mainly based on light and uses geometric ray tracing methods to study the propagation rules of light in media and the imaging characteristics of optical systems. Geometric optics is the basic chapter of "College Physics" and "Engineering Optics". This experiment optimizes and upgrades the original geometric optics measurement experiment, adopts engineering testing methods, and uses parallel light tubes to measure important parameters of the optical system, providing a good experimental platform for undergraduates to understand and master geometric optics content.
