Abstract

This paper describes an underwater optical flying-spot scanning sensor system designed to provide an optical map of the ocean floor. Designed primarily as aid in underwater search and mapping, it provides a real-time optical picture of a 400-foot-wide swath width of the sea floor when towed from a 120-foot height off the bottom. The system inherently incorporates a means of sufficiently reducing the detrimental effects of backscatter to allow fast area search through the use of a wide (120°) field-of-view. Reasons for the choice of the approach taken to reduce backscatter are given along with details of the specific approach and a sample of preliminary data taken in an underwater test facility.
