Abstract
A laser method of measuring the particle mean size and dust concentration by laser optics is presented in this paper, the method is based on Fraunhofer diffraction theory which is the approximation of Mie scattering within the forward Fraunhofer diffraction lobe, and Rosin-Rammber function is used to describe the particle size distribution in dust flow in advance. Compared with the values by the Sample-weight method, the measurement results have a reasonable agreement. The present work has demonstrated this method will be probably used to monitor the parameters of two phase flow.
