摘要

为了更好地保护沿海环境和相关的自然和人造资产,迫切需要的是快速识别可疑海底物体的能力。即使使用最先进的水下摄影技术,通常阴暗的港口和沿海水域也使这项任务几乎不可能完成。然而,如果串行激光照明器和单元件探测器子系统以分布式配置(可能在多个水下机器人平台之间)运行,则可以实现更简单的系统架构,从而扩展操作范围,并迅速将高质量的图像和其他信息传输到远程位置。为了更好地了解这种分布式海底成像技术在自然水域的潜在性能,也为了确定在这种操作中激光照明器和探测器子系统之间是否需要精确对准,海港分支海洋研究所的海洋能见度和光学实验室最近开发了一种分布式激光成像仪的原型。该系统最近在佛罗里达东海岸的一系列非常浑浊的河口条件下进行了测试。本文将介绍和讨论这些实验的结果以及该分布式激光成像仪原型的描述。

Extended range distributed laser serial imaging in turbid estuarine and coastal conditions
One pressing need in the drive to better secure the coastal environment and associated natural and manmade assets is the ability to rapidly identify suspicious undersea objects. Typically murky harbor and coastal waters render this task nearly impossible, even with the most sophisticated underwater camera technologies. However, simpler system architectures that can extend operational range and also rapidly transmit high-quality imagery and other information to remote locations could be realized if a serial laser illuminator and single element detector sub-systems are operated in a distributed configuration, possibly among multiple undersea robotic platforms. To gain a better understanding of the potential performance of this distributed undersea imaging technique in natural waters, and also to determine if precise alignment is required between laser illuminator and detector sub-systems during such operations, the Ocean Visibility and Optics Laboratory at Harbor Branch Oceanographic Institute recently developed a prototype distributed laser imager. The system was tested recently in a range of very turbid estuarine conditions off the east coast of Florida. Results from these experiments as well as a description of this distributed laser imager prototype will be presented and discussed in this paper.
