摘要
为了进一步改善测量大气粉尘浓度的方法,论文研究了基于光散射与透射原理为基础的大气粉尘浓度测量方法。首先对光在粉尘环境中的传播特性进行了分析与讨论,在此基础之上,深入研究了粉尘微粒对光的散射与透射作用,得出了散射角度对光散射的影响。为了便于展开实践研究,该文采用菲涅尔透镜,将光源变为平行光源,以便更高精度地实现对于测量区域粉尘的浓度。实验结果与分析表明,该文采用的方法能够实现对粉尘的高精度检测,实验结果与理论分析基本一致。
In order to detect dust concentration in the atmosphere and industrial production,a light transmission combined with a light scattering detection method is proposed in this paper.A light transmission and scattering in the dust environment is analysed and discussed.The scattering and transmission effect of dust particles on light is studied,and the effect of scattering angle on the light scattering is obtained.The Fresnel-lens used to convert point light into parallel light,and can realize the detection of the dust concentration in a large area.The experiment results show that the method can achieve high accuracy detection of dust.And the experimental results are in accord with the theoretical analysis.
