虹和霓是太阳光在雨后天空中的大量小水滴中发生折射与反射后形成的现象，具有重要的研究意义. 本论文用直径合适且相等的实心匀质透明球代替水滴，用复色光源以合适的角度与距离照射，使虹、霓现象复现. 在此基础上分别进行了单球、双球复现虹霓现象及多球实现虹霓叠加的实验，利用光谱分析技术测量复现出的虹霓光谱. 本文所设计的装置集现象演示与参数测量于一体，在光学实验教学和科普教育中具有重要的实际应用价值.

 Rainbow and neon are phenomena formed by sunlight refracting and reflecting in raindrops, which has important research significance. In this paper, solid homogeneous transparent balls with appropriate and equal diameter are used to replace water droplets, and multicolor light source is used to illuminate at an appropriate angle and distance to reproduce the phenomenon of rainbow and neon. On this basis, the experiments of reproducing rainbow phenomenon with single-ball and double-ball and realizing rainbow superposition with multi-ball are carried out respectively. The reproduced rainbow spectrum is measured by spectral analysis technology. The device designed in this paper integrates phenomenon demonstration and parameter measurement, and has important practical application value in optical experiment teaching and popular science education.
