为了解决水下观测平台的多样性与搭载仪器工作模式的匹配问题，将深海集成化自容式拉曼光谱仪（ deep ocean compact autonomous Raman spectrometer， DOCARS）的工作模式分为配置外围设备的工作站模式和单一探测功能的传感器模式。在分析DOCARS系统结构的基础上，对这两种工作模式进行了详细设计。系统先后于2009年和2015年搭载海鸟采水器框架和“发现号”水下机器人（ ROV）进行海试，前者按工作站模式工作，成功获得了自带样品的拉曼光谱和深海工作图像；后者工作在传感器模式，随ROV下潜的4个潜次中，以1 Hz的频率采集了移动路径上海水的剖面光谱数据。海试结果证明了两种工作模式在搭载相应观测平台时的有效性和稳定性。%A newly developed system called deep ocean compact autonomous Raman spectrometer ( DOCARS) can be deployed on various underwater observation platforms. To meet the diversity requirement of the underwater obser-vation platform and solve the matching problem of the working modes of the deployed instrument, two operation schemes were developed for DOCARS on the basis of deployment conditions and specific applications to function as either a benthic instrument node or a chemical sensor. Several peripheral units were operated in the instrument-node scheme. In another scheme, DOCARS operated only as a Raman spectrometry-based sensor. In sea trials in 2009, the first developed DOCARS, which operated as an instrument node, was mounted on the framework of a Seabird water sampler. The Raman spectra from the releasing samples and the monitoring images of performance were ob-tained. In the summer of 2015, the upgraded DOCARS was deployed on the remotely operated vehicle ( ROV) Fax-ian, performing well as a chemical sensor with a detection rate of 1 Hz. Depth profiles of Raman spectra were re-ceived along the ROV’ s moving path on its four dives. The sea trials prove the effectiveness and stability of the two operation schemes on specific platforms.
