海洋中的悬浮颗粒在全球营养循环中起着重要作用。本文提出了一种非接触式快速识别海洋颗粒物的新技术。提出了一种数字全息和拉曼光谱相结合的方法，用于海洋颗粒物的现场连续监测，特别是在颗粒物密度极低的深海中。使用准直的连续波激光束照射位于20 cm水通道中的颗粒，所述激光束用于拍摄全息图和拉曼光谱以识别悬浮材料的形状、尺寸和组成。使用一个紧凑的系统，我们已经展示了大量水中塑料颗粒的形态和化学分析。此外，我们还开发了原位装置，并首次在水深900米的深海进行了测试。该技术将有助于了解全球尺度的海洋颗粒物分布。
Suspended particles in the ocean play an important role in global nutrient cycles. In this paper, a novel technique for the non-contact fast identification of marine particles is reported. An integrated method of digital holography and Raman spectroscopy aiming at in-situ continuous monitoring of marine particles, particularly in the deep sea where the density of particles is extremely low, is proposed. A particle located in a 20 cm water channel was illuminated using a collimated continuous wave laser beam which is used to take both a hologram and Raman spectrum to identify the shape, size and composition of the suspended material. Using a compact system, we have demonstrated the morphological and chemical analysis of plastic particles in a large volume of water. Furthermore, we have developed the in-situ device and tested it in the deep sea at a water depth of 900 m for the first time. The technique will contribute to the understanding of global-scale marine particle distributions.
