Underwater Imaging System Performance Characterization
Abstract
This report summarizes the results of a computer study that was initiated in order to study the performance and recommend possible improvements to the Mine Neutralization Vehicle System. The computer model UNCLES which was written by the Woods Hole Oceanographic Institution was used for this purpose. The results indicate that as currently configured, the vehicle will be able to see no more than 1 attenuation length in range. The study of the possible improvements in vehicle configuration indicate that large improvements in image visibility can be had for small changes in camera/light configurations. Movement of the lights aft, narrowing of the beam patterns, and adjustment of the pointing angles can be used to double the imaging performance in almost all environmental conditions. Additional studies of advanced sensors indicate that the current generation of commercial lasers are too low in power to permit extended visibility. As a means of extending the imaging range of the vehicle a system that employs scanning light beams in concert with image processing is suggested. The computer simulations of this configuration indicate that visibility to 5 attenuation lengths will be possible with this system.
