Abstract
This paper constitutes an update on our efforts to develop an underwater laser-based imaging system (UWLIS). The work is being performed under contract from the Naval Sea Systems Command Office of Salvage and Diving (NAUSEA/00C) in order to provide instrumentation that will improve the visibility range available to deep-ocean (1500-6000 m) submersible vehicles during ocean-floor search-and-salvage operations. In general, these submersibles are remotely operated vehicles (ROV) that currently employ high-intensity floodlights and low-light-level TV cameras to produce video images of the seafloor, which are relayed to the mother ship to allow target identification. Often, these floodlight-based systems require that the ROV come within 6 to 10 m of the target in order to positively identify it. This poses both a risk of damaging the vehicle on outcropping seafloor terrain features and an increase in mission cost due to the time lost on maneuvering to identify false targets. Given that salvage-operation costs typically range from $1000 to $3000 per hour, a system that would improve the visibility range from 10 to 100 m would save thousands of dollars and greatly increase the probability of success of these missions.
