摘要
本文基于2021年全国大学生物理竞赛(创新赛)的命题之一“霓虹现象的设计与重现”,设计了一种基于超连续谱激光器的霓虹重现方案,得到了很好的实验效果.相比已报道的霓虹实验,本文的方案既能呈现清晰的霓虹现象,又能定量测量霓虹的偏振和干涉等波动光学特性.本实验从生活中常见的物理现象出发,契合大学物理教学中的波动光学内容,是一个集趣味性和探究性一体的课题物理实验教学案例.
One topic of 2021 CUPEC is“the design and reproduction of rainbow phenomenon”.In this paper,an experimental facility based on supercontinuum laser to reproduce rainbow is designed,which can give a good demonstration.Compared to reported rainbow experiments,the designed facility not only show rainbow phenomenon clearly,but also can be used to quantitatively analyze rainbow wave optics properties,including polarization and interference.This experiment is based on the common physical phenomena in daily life,but it is consistent with the wave optics of college physics.It can be as an interesting and exploratory physics experiment.
