Abstract

Luminous line filaments were photographed at the Diamond Island (Lake Winnipesaukee) Station of the Visibility Laboratory at ranges up to 7½ water-attenuation lengths. Image widths were ⅓ mrad or less at ranges from three to six attenuation lengths. It is concluded that optical transmission in natural surface waters may be considered to consist of separable scattered and unscattered light components, and signal processing may be used to alleviate the image deterioration caused by scattering in the water.
