Third- and Fourth-Order Rainbow Fringe Characteristics of Homogeneous Ellipsoid Droplets
摘要
基于矢量光线追踪(VRT)模型, 研究了均匀椭球形液滴三阶和四阶彩虹区域的光学焦散结构, 详细探究了光学焦散结构的演化过程, 得到了三阶彩虹条纹的模拟结果、条纹曲率以及三阶彩虹和双曲脐条纹尖点焦散位置与椭球度的关系。
Abstract
Based on the vector-ray tracing (VRT) model, the optical caustic structures of homogeneous ellipsoid droplets in the third-order and fourth-order rainbow regions are studied. The evolution process of the optical caustic structure is investigated in detail. The simulated result and fringe curvature of the third-order rainbow fringe as well as the relationship between the cusp location of the third-order rainbow and hyperbolic umbilic fringes and the aspect ratio are obtained.
