This project investigates a novel problem in inverse scattering, the determination of the shape and refractive index of a transparent object from the position of the rainbow caustics of light scattered by it. The work will examine experimentally the rainbow position of light scattered from a transparent cylinder with a non-circular cross section as a function of the angle of rotation. Preliminary results indicate that the cross sectional shape is encoded into the coefficients of the Fourier series expansion of the deviation of the primary and secondary rainbow angles. An accompanying model is used to explain the data.

本计画研究逆散射中的一个新问题，即由透明物体散射光的彩虹焦散线的位置来决定透明物体的形状和折射率。 这项工作将通过实验研究从具有非圆形横截面的透明圆柱体散射的光的彩虹位置作为旋转角度的函数。 初步结果表明，横截面形状被编码到主和次彩虹角偏差的傅里叶级数展开的系数中。 一个附带的模型被用来解释数据。
