Abstract :
The traditional scattering-based optical method is not perfect because the space structure of dust concentration sensor and the response performance can not be balanced. In this paper, we focus on the research and improvement of technical problems. Built on the basis of previous studies, an improved photoelectric sensor to measure dust concentration which is based on the method of optical-backscattering is put forward.
