Abstract

Underwater optical range-gating, designed to extend the maximum range of underwater photography, has been demonstrated in a series of experiments conducted at the NOTS Morris Dam Test Range. With black tape on Scotchlite being used as a target. comparison photographs of gated and non-gated exposures showed promising improvement in the clarity of the gated pictures. This was attributable to the elimination of most of the backscattered light. A description of the apparatus and a sample of the data obtained at various target distances are presented and discussed.
