Abstract : In order to provide a high-resolution underwater-ranging capability for scientific measurement, a commercially available optical-ranging system is analyzed for performance and feasibility. The system employs a structured- lighting technique using a laser-light plane and single-camera imaging system. The mechanics of determining range with such a system are presented along with predicted range error. Controlled testing of the system is performed and range error is empirically determined. The system is employed in a deep-sea application, and its performance is evaluated. The measurements obtained are used for a scientific application to determine seafloor roughness for very-high- spatial frequencies (greater than 10 cycles/meter). Use and application recommendations for the system are presented.
