Underwater Laser Surveying System

摘要

The report describes the development of an Underwater Laser Surveying System usable by two divers for plot layout, bottom contour mapping and other underwater surveying missions. The portable cold-cathode argon laser is the central element to the system. The supporting test program demonstrated the feasibility of the system for plot layouts to 6 inch accuracy and contour elevation to 1.2 inch accuracy over ranges of up to 100 feet. Operating procedures and maintenance instructions for the system are also included. (Author)
