群体粒子场圆偏入射光侧向散射的角分布实验研究(英文)

Experimental Study on the Angular Distribution of Radiation Side-scattered by the Multiple Particle Field Using Circularly Polarized Incident Light

对圆偏振光入射到群体粒子场时侧向散射光随角度分布的特性进行了实验研究,散射介质为直径0.065μm和1.24μm的粒子与过滤的蒸馏水所构成的不同浓度的悬浮液。实验结果表明,粒子侧向散射光的各种成分在探测平面内相对散射角度始终呈现对称分布的规律,而随着粒子尺寸、浓度、探测深度的变化,散射光强也相应出现变化,但变化不明显。

An experimental study on the angular distribution properties of radiation side- scattered by the multiple particles when using circularly polarized incident light was undertaken. The scattering medium is the suspending liquid consisting of various concentrations of particles which are either 0. 065μm or 1.24μm in diameter and which were mixed into filtered, distilled water. The experiment results show that in the detected plane the intensity distribution of each component of the side - scattered light is angular - symmetric, and the intensity variation is slight as particles＇ sizes, concentrations, or detecting depths varying.
