Abstract

Conventional optical imaging systems have limited performance in Degraded Visual Environments (DVE) such as dust, fog, sand, and turbid water due to multiple scattering of the light on the path from the source to the target. Their large platform size also makes them unfavorable for compact, autonomous systems. In recent years, researchers at NAVAIR in Patuxent River, MD have developed a compact submersible laser imaging system based on a multistatic system architecture, allowing the source and multiple receivers to reside on separate, smaller, independent platforms. The system geometry can be better optimized for the environment, allowing it to obtain high quality imagery through much higher attenuation lengths (between the target and receiver) when compared to conventional imaging systems. The smaller source also lends itself to integration into an autonomous underwater vehicle (AUV). A compact, multistatic imaging system designed for integration into a REMUS 600 AUV has been developed and is currently being tested in a laboratory environment. System design and laboratory test plans will be presented.
与AUV平台兼容的多静态光学成像系统
传统的光学成像系统在退化的视觉环境(DVE)中,如灰尘、雾、沙和浑浊的水,由于光在从光源到目标的路径上的多次散射,性能有限。它们的大平台尺寸也不利于紧凑的自主系统。近年来,位于马里兰州Patuxent River的NAVAIR公司的研究人员开发了一种基于多静态系统架构的紧凑型水下激光成像系统,该系统允许源和多个接收器驻留在独立的、更小的独立平台上。与传统成像系统相比,系统几何形状可以更好地针对环境进行优化,从而通过更高的衰减长度(目标和接收器之间)获得高质量的图像。较小的光源也适合集成到自主水下航行器(AUV)中。一种紧凑的多静态成像系统被设计集成到REMUS 600 AUV中,目前正在实验室环境中进行测试。将介绍系统设计和实验室测试计划。
