介绍了用于海洋叶绿素荧光原位探测的原型激光/光纤系统的首次海上试验。来自船载氩激光器的488 nm辐射通过20 μ l 200 μ m芯光纤传输到安装在微结构轮廓仪（快速取样垂直轮廓仪）上的远端。后向散射的荧光发射信号通过相同的光纤收集并在船上处理。一系列的测量结果表明，（1）成功的隔离船舶引起的振动，可以实现使用我们的光学工作台框架，以保持光学对准;（2）环境叶绿素浓度可以在原位检测;（3）一个拉曼散射信号从水也可以检测到，并应提供一个内部标准，叶绿素荧光可以校准。
The first seagoing test of a prototype laser/fiber-optic system for in situ detection of ocean chlorophyll fluorescence is described. Radiation at 488 nm originating from a shipboard argon laser was transmitted through 20 of 200-microm core optical fiber to the distal tip mounted on the microstructure profiler, the Rapid Sampling Vertical Profiler. The backscattered fluorescence emission signal was collected through the same fiber and processed on board ship. A series of measurements indicated that (1) successful isolation of shipinduced vibrations could be achieved using our optical bench framework to maintain optical alignments; (2) ambient chlorophyll concentrations could be detected in situ; (3) a Raman scattering signal from water could also be detected and should provide an internal standard against which chlorophyll fluorescence may be calibrated.
