本文介绍了一种用于流动气流中单个气溶胶粒子分类的新型多角度光散射仪器。在一个球形室的表面上的16个散射角的同时测量允许确定各种光学可观测值，用于每个测量颗粒的后续表征。测量了直径为0.2 - 4.0微米的颗粒，并以超过200个颗粒/秒的速率收集了数据。显示了来自聚苯乙烯胶乳颗粒、液滴和不规则颗粒的数据。球形粒子的数据进行了比较，理论计算，并用于确认测量的有效性，以及一个强大的校准程序。
A new multiangle light scattering instrument is described for the classification of single aerosol particles in a flowing gas stream. Simultaneous measurement at sixteen scattering angles over the surface of a spherical chamber permits determination of a variety of optical observables useful for the subsequent characterization of each measured particle. Particles of 0.2 - 4.0-microm diameter have been measured and data collected at rates exceeding 200 particles/s. Data from polystyrene latex particles, liquid droplets, and irregular particles are shown. Spherical particle data are compared to theoretical calculations and used to confirm the validity of the measurement as well as a powerful calibration procedure.
