本文研究了多色平面光波入射到各向异性粒子上的散射。与光波被各向同性粒子散射不同，各向异性粒子的旋转会引起谱线的频移。导出了散射场频谱的解析表达式，并给出了数值例子。我们提出了一个应用程序，各向异性散射体的旋转角速度可以通过测量散射场的光谱来缩放。
We investigate the scattering of a polychromatic plane light wave incident upon an anisotropic particle. It is different from light wave scattered by an isotropic particle that the frequency shifts of spectral lines will be induced by the rotation of the anisotropic particle. The analytical expression for the spectrum of the scattered field is derived and numerical examples are also illustrated. We suggest an application that the angular speed of rotation of the anisotropic scatterer can be scaled by measurement of the spectrum of the scattered field.
