为了检测水中有害/杂质颗粒物，对水中颗粒物空间分布监测系统进行了开发研究。在研究中，通过激光片光照明，可视化了水中颗粒的空间分布和空间行为。通过对可视化图像的分析，对每种尺寸的颗粒数量进行计数。图像分析显示了颗粒的粒度分布。为了验证该技术，使用微米尺寸的单分散聚苯乙烯胶乳（PSL）颗粒。从可视化图像中获得了每个颗粒图像的颗粒尺寸和像素面积之间的对应关系。此外，还尝试了利用光学图像处理进行图像分析。在该技术中，可以真实的实时地检测具有特定尺寸和/或形状的目标颗粒。结合这些技术，可以对供水系统中特定颗粒的空间分布和数量进行真实的实时监测
In order to detect the hazardous/impurity particle in the water, the developmental research for the monitoring system of spatial distribution of particle in the water has been carried out. In the research, the spatial distribution and the spatial behaviour of particle in the water is visualized by the laser sheet light illumination. The number of particle in each size has been counted by the analysis of the visualized image. The size distribution of particle has been displayed by the image analysis. In order to validate the technique, mono-dispersed Poly Styrene Latex (PSL) particles those are micron size are used. The correspondence between the particle size and the pixel area of each particle image has been obtained from the visualized images. Besides, the image analysis by the use of optical image processing has been trialed. In the technique, target particle that has specific size and/or shape can be detected in real time. Combining these techniques, specified particle's spatial distribution and the number can be monitored in real time in the water supply system
