摘要
以产生虹现象的小水珠的色散原理为基础,系统分析了透明圆柱形截面纤维在平行光照条件下,一次内表面反射光中笛卡尔线的色散机理与特征,证明了透明圆柱形截面纤维与水珠产生虹现象的色散机理与特征是相似的。
In this paper a systematic analysis is made about the principle and characteristic of the round fiber dispersiveness based on the dispersive principle of the little drips which can produce rainbow. It is proved that the dispersive principle and characteristic of the transparent and round fibers are similar with the drips producing the rainbow, when the transparent and round fibers are irradiated in parallel light.
