虹与霓设计与再现

The Design and Reproduction of Rainbow and Neon

提出一种崭新的虹与霓现象观测方法,通过将分光计与光源结合改装,以自制“光学透镜与添加装置”为核心,实现了对光源光强、虹的长宽、折光率等参数的动态调整,能够稳定呈现曲率可调的弯曲彩虹现象,解决了传统装置参数调节困难、霓虹呈现效果单一的问题。该装置体积小、方便携带,为引导使用者多维度全面学习霓虹呈像原理提供了全新的启蒙思路。

A new observation method of rainbow and neon phenomenon is proposed.By refitting the spectrometer with the light source and taking the self-made“optical lens and adding device”as the core,the dynamic adjustment of the light intensity of the light source,the length and width of the rainbow,the refractive index and other parameters is realized,which can stably present the curved rainbow phenomenon with adjustable curvature,and solve the difficulty in adjusting the parameters of the traditional device Neon presents the problem of single effect.The device is small and easy to carry,which provides a new enlightenment idea for guiding users to comprehensively learn the principle of neon imaging in multiple dimensions.
