Abstract : This report contains evaluations of various proposed methods of illumination intended to achieve improved underwater photography. In a solicited proposal submitted by Tetra Tech Inc, an illumination system called 'Volume Scanning' was described. In this concept a pulsed Xenon light source supplies a fan-shaped beam. The beam is made to scan the subject in synchronism with a mechanically-coupled moving camera. Other concepts including laser range gating, polarization and photographing the screen of a special closed circuit television system are discussed. It was recommended that the contractor construct a working model incorporating the Volume Scanning principle for further test and evaluation. (Author)
