Abstract: | The purpose of this paper is to develop an approach using digital laser holographic imaging for measuring and calculating geometrical parameters of marine plankton. It is very important for study of marine plankton and it facilitates the analysis of marine plankton. Using this approach, we obtained geometrical parameters of marine plankton including perimeter, equivalent diameter, lateral size and so on. It is found that a measurement aberration is less than 8% for copepods sample by using collimating reference wave. |
