摘要
海洋浮游生物是一个复杂而庞大的生物群落,种类繁多、数量庞大,对海洋环境、生态、渔业及海洋基础科学研究具有重要的科研价值与现实意义。为实现对海洋浮游生物和颗粒物的实时原位,高分辨率,非侵入式成像,研发了OUC-HoloCam200水下原位同轴数字全息浮游生物探测系统。OUC-HoloCam200基于同轴数字全息技术,具有高精度、大景深的优点,仪器结构紧凑、集成度高,易于安装在各种水下观测平台上。该仪器可在海洋生物学、海洋光学、海洋环境监测等领域发挥一定的作用。OUC-HoloCam200已在南海近岸地区进行了浅海测试,并已连续工作超过48 h,在海试期间,已记录超过5.4万张高质量的原位全息图。
Marine plankton is a complex and large biome, with various species and large quantities, has important scientific research value and practical significance for marine environmental, ecology, fisheries, and oceanographic basic research. Here we present a system named OUC-HoloCam200, which capable of non-invasively imaging planktons and particles in situ at nearly micrometre resolution. OUC-HoloCam200 is based on digital holography technology, which has the advantages of high precision and large depth of field, and is compact and highly integrated, making it easy to mount on various underwater observation platforms. It can play a certain role in the development of marine biology, ocean optics, marine environmental monitoring and other fields. OUC-HoloCam200 have been deployed in the nearshore area of South China Sea and have worked continuously over 48 h, during the sea trial, more than 54 thousand high-quality in-situ holograms had been recorded.
