Paper Abstract

A mathematical model, Visibility Evaluation of Underwater Systems (VEUS), used to predict the optical response of deep-sea viewing systems, is under development. The model predicts the scene modulation (target contrast), target irradiance, and total exposure at the focal plane as a function of the following: (1) viewing and lighting geometry, (2) spectral water characteristics, (3) spectral light source emittance, (4) spectral camera and film characteristics, and (5) target and background reflectance. The model sums light energy over the visible spectrum contributed by discrete water slabs between the viewing system and the target. Water clarity characteristics (volume scattering function, diffuse attenuation coefficient and volume attenuation coefficient) were measured in several different areas and this data formed the basis for a test comparison between the mathematical model and actual photographs taken with TELEPROBE, a deep-tow viewing system. This test has shown the model produces data that agree with photographic response.
