Abstract

A laser-diode based optical system which can measure aerosol particle size and concentration is described in this paper. The light scattering response characteristics of the system are calculated based on Mie light scattering theory. Some experimental results show that the system has high counting accuracy, efficiency and reproducibility, and suitable for verification of cleanliness class and measurement of ambient aerosol size distribution.
