A Monograph on Applications of Multicolor Dye Tracers and Multispectral Photography to Coastal Water Mapping,
Abstract
A new concept has been evolved for investigation of the morphology and 3-D transport of turbidity cells. The basic idea is to make use of the variable extinction (water penetration) depths for different bandwidths (plus or minus 100A) of the image forming light scattered through relatively turbid waters, and the narrow band slicing of the visible spectrum feasible with interference filters. The method of employing these phenomena and multiband imaging techniques is to make a multicolored dye release of dyes with characteristic spectral 'signatures' as viewed with narrow band (interference) filters. These releases are to be made at depths which match the extinction depths for light in the respective dye characteristic 'signature' bandwidths. The resulting dye patches are then imaged through narrow band interference filters matched to the characteristic spectral signature (and extinction depths) for each type of dye. (Author)
