Plate III Comparison of four images (scale is 1:25) of a section of sea bed using (a) open channel (elastic scattering) imaging, (b) red fluorescence imaging, (c) yellow fluorescence imaging, and (d) pseudocolor fluorescence imaging. The elastic scattering image simulates the results of a standard monochromatic laser line scan. In the three fluorescence images, the color and sand fluoresce strongly, while the man-made objects block the fluorescence signal and appear dark. Conse- quently, the fluorescence signal has greater utility for discriminating between natural materials (suach as sand or coral) and man-made materials (such as antipersonnel mines).
