基于粒子受激散射的烟与气溶胶粒子属性识别

Attribute identification of the smoke based on particle scatterance from the aerosol particle

介绍了粒子散射相关理论以及激光粒子信号多角度检测装置的构成与基本原理,并详细描述了对烟与干扰气溶胶粒子的多角度散射特征进行采集、处理和分析的过程。实验证明,通过多路比值的交叉对比可以区分不同类型粒子,也就说明通过角散射比值区别烟雾与干扰粒子是可以实现的。

Some theories related to particle scatterance and the structure as well as the fundamental principle of the facilities for testing laser signal from multiple angles have been introduced. The process of data collection, treatment and analysis of the multiple angles scatterance properties that intervenes the smoke and aerosol particles. It has been proved that different kinds of particles can be identified through crossbalancing of the multiplex ratios.
