数字全息水污染微污染物Digital Holography Water Pollution Micro Pollutant



A key step in the restoration of rivers and lakes is to identify the major pollutants such as mi-cro-organisms, oil, and of course chemicals, so that the source can be identified and remedies can be devised. A general method for rapidly monitoring pollutants of micrometer scale is still lacking. We use 4D digital holographic microscope with point laser source to study the typical water sample taking from Pearl River within Guangzhou. Copepods, rotifer, mineralized skeleton of radiolarian protozoa, dead cells, micro-oil drops are identified. The speeds of copepod and rotifer are measured to be 280 and 100 micrometer per second. The hazard of high-density micro-oil drops is noted.
