SMALL-ANGLE SCATTERING OF LIGHT BY OCEAN WATER

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.
