一种新的散射光能谱法测量颗粒粒径的方法

A Novel Method Using Light Scattering Energy Spectrum for Particle Size Analysis

基于光散射原理，提出了一种新的测量颗粒粒径大小及分布的方法。与传统的光散射式激光测粒仪不同，本方法以白色光为光源，仅采集一个空间立体角内的散射光能信号，经反演算后求得被测颗粒的粒径及其分布。给出了这一方法的理论分析、数值模拟以及实验研究。

Based on the light scattering principle, a novel method for particle size analysis is presented in this paper. As distinguished from the traditional light scattering based laser particle sizers, a white light is used as the light source and the scattered light energy within only one solid angle is collected. The particle diameter and its size distribution are then acquired from the inversion calculation. Theoretical analysis, numerical simulation as well as the experimental investigation are presented and discussed.
