Design of laster plankton optical detecting system for oceanic fisheries

摘要

This paper designs a plankton particle diameter measurement instrument based on laser projection, which uses laser light source to irradiate the photodiode array, and then collects plankton shape data with the shielding effect. The system reconstructs the morphological characteristics of plankton by using the time axis scanning, to complete the collection and analysis of marine plankton particle size information. The proposed plankton particle size in situ detector can be used for the investigation in oceanic fisheries resources.
