摘要：
This paper presents a design of particle detection system based on optical transmission and scattering method. In this setup, a laser with emitting wavelength of 671 nm is employed. The sample particles are 3.03 um and 7.07 um polystyrene microspheres. Based on Mie scattering theory and Beer-Lambert law, the particle size and particle number concentrations against the scattered light intensity and transmitted light intensity are studied experimentally. The experimental results show that the scattered light intensity increases with the increasing of particle size and particle number concentrations. However, the transmitted light intensity decreases with the increasing of particle number concentrations. In our future work, this system will be applied to platelet aggregation detection. By detecting the transmitted light intensity and scattered light intensity simultaneously, this detection system can achieve more accurate detection.
