CONTINUED DEVELOPMENT AND DEMONSTRATION OF A LASER LINE SCAN LIDAR SYSTEM (LLSLS) ON AN AUV
Abstract
Under funding from the Office of Naval Research Dr. Jules Jaffe~s laboratory has developed aLaser Line Scan LiDAR System (LLSLS) for imaging objects on the sea floor. This is animportant task for remediation of sea floor explosives. Competing techniques, such as acoustics,have not yet achieved the level of unique identification that would allow them to provide theunambiguous identification that optical techniques provide. In the realm of optical techniques,Laser Line Scan Systems provide the highest resolution possible as narrow transmit beamscoupled with a small receiver field of view result in better image quality. In addition, using ashort pulse of light permits the near-field scatter to be gated out, thus providing much highercontrast than other methods. Simply put, Laser Line Scan LiDARs are the most sophisticatedand highest performing imaging systems for oceanic imaging in existence today. Based onextensive quantitative testing, our own system~s performance exceeds that of all prior systems, asverified by the conclusions of several experts. We view its potential use in both Navy andcivilian systems as a major ~transition~ success for our ONR program and hereby will performwork to: (1) Continue tests of the system on a REMUS 600 vehicle with our collaborator, theWoods Hole Oceanographic Institution; (2) Perform analysis on the data taken during these teststo determine resolution as a function of water characteristics; (3) Explore advanced signal andimage processing methods to increase interpretation of the data; (4) Research the extendedcapabilities of putting this type of system on a REUMS 100 AUV to provide options for futurework; and (5) Communicate these findings to the Naval community that stands to benefit greatlyfrom the use of these types of systems.
