SMALL-ANGLE SCATTERING OF LIGHT BY OCEAN WATER

Abstract

A semi-quantitative analysis of the mechanisms involved in very intense, small-angle forward scattering of light by ocean water. Two important mechanisms described are (1) suspended biological particles in the water having an index of refraction close to that of water and (2) deviations of the light beam due to large-scale refractive index variations. When the modulation transfer function (MTF) associated with these mechanisms is calculated, a complete statistical description is obtained for the transverse coherence properties of the beam as a function of the propagation distance. Some numerical estimates are given of the MTFs that might be expected under various conditions.
