Development of a Laser Line Scan LIDAR Imaging System for AUV Use

Abstract

Abstract : Our overall goal is to develop a next generation underwater optical imaging system for deployment on an Autonomous Underwater Vehicle. The system is predicted to have extended range performance ( 3 total attenuation lengths). This project is an extension of work that was initiated after the successful outcome of SBIR Phase I and II [topic N04-176, Aculight] programs that demonstrated that a new type of fiber laser could be developed that would fulfill the necessary role in a next generation underwater Laser Line Scan System for deployment on an AUV. Here, funds have been allocated to build two underwater pods that are suitable for inclusion deployment on Autonomous Underwater Vehicles. Here, we describe work accomplished during the period October 1, 20010 August 31, 2011. During this period, the project has progressed as we (Lockheed Martin Aculight, LMA, and SIO) have designed, built, and tested the hardware optical and electronic components for the final system. System tests by LMA have confirmed that the performance of the final configuration optical components will meet system specification goals. SIO supervised the assembly and delivery to LMA of the system chassis. Work with the Metron Corporation has also been collaboratively progressing as they have been working towards the creation of a model to predict system performance. As a result of choice of the Hydroid Remus 600 vehicle for our deployment platform and have been working with Hydroid to prescribe both the system s package and its incorporation into the Hydroid Remus 600 vehicle. This information has been incorporated into our expansion proposal to integrate the system into the Hydroid vehicle. We categorize our planned work as Phase III of a three-phase development. The jointly developed end product from Phase II is a laser imager that SIO will integrate into the Hydroid Remus 600 Vehicle AUV for at-sea testing.
