| 摘 要： | 基于数字图像处理技术和光学粒子散射理论，研制了具有非接触式、全场测量、被测面积大和成本低等特征的瞬态浓度场定量光学测量系统，其可以测量瞬态浓度场的相对值，经过标定也可以测量绝对值．实验结果表明，该系统与传统的接触式单点浓度测量方法相比，具有显著的全场瞬态测量的优越性，应用前景广阔。

| Abstract: | Based on digital image processing technique and optical scattering theory of particles,an optical measurement system for experimental investigation on instantaneous concentration fields of flows is presented.The system is characteristic of non-intrusion,full-field measurement,wide measurement region and cheap cost.It is directly applied to the environment wind tunnel in the University of Shanghai for Science and Technology.The results are demonstrated to show that the system is feasible and effective.The system has wide applications and it is useful for experimental investigation on fluidic flow,communication pollution dispersion,and street canyon pollution. |
