SM 2000 Laser Line Scan System (LLSS)
The SM 2000 Laser Line Scan System (LLSS) is towed just above the sea floor and is attached by an electrical cable to search ship. The system, using blue-green laser light, produces detailed video images over 10 to 200 foot-wide swaths of the sea floor, depending on visibility, and can display details of objects less than one-half-inch in size. It can cover an area up to five times larger than conventional underwater cameras while retaining fine detail. The LLSS was built by Oceanic System Unit of Northrop-Grumman Corp. in Annapolis, Md., and has been used by Science Applications International Corp. of San Diego since 1992 for environmental surveys and underwater inspections of oil platforms, pipelines, and sewage outfalls.
