| Outline of Final Research Achievements |
This study proposed a new imaging technique to measure three dimensional distribution of suspended sediment. In this technique, color pattern illumination, which has different color layers, is projected from a PC projector, and scattered light by the suspended sand are recorded by a digital camera. Based on the intensity distributions of each color in the image, two dimensional distributions of number density of the sand are obtained for each color layer, and a three dimensional distribution is composed from these two dimensional distributions. In a series of physical test, reasonable three dimensional distributions were successfully obtained.
