Underwater Imaging Studies.

Abstract

This project was concerned with advancing the understanding of both the theoretical underpinnings of underwater image formation theory and also the experimental development of a new system for obtaining three dimensional information about ocean optical properties. Theoretical results from a Monte Carlo simulation of underwater radiance fields the average cosine of the radiance field does not achieve its asymptote for an omnidirectional source, even after 15 attenuation lengths. In addition, limits to the computation of the absorption coefficient, using an omnidirectional light source are explored. Experimental results of lab simulations of a volumetric imaging system based on fluorescence emission from a sheet of stimulating light laser light indicated that the system can be used to measure the 3-dimensional distribution of chlorophyl-a over a broad range of concentrations.
