An Experimental Facility for Laser/Acoustic Applications.

Abstract

This report describes the Experimental Laser/Acoustic System (ELAS) developed by Applied Science Technology, Inc., for applications involving the C02 laser/acoustic technique. This system is composed of a C02 laser transmitter to generate the acoustic signals in water, an acoustic receiving system, signal recording and analysis equipment, and a computer. A detailed description has been given for each of these subsystems. Laboratory and field measurements have used this system to investigate the feasibility of the laser/acoustic technique for remote sensing applications of shallow turbid water bathymetry, underwater object (mine) detection, and soil moisture determination. The ELAS is an extremely versatile system, as it is not tied to any specific transmitter or sensors. Therefore, there are numerous other applications involved with navigation and communication which this system could be used to investigate. Brief summaries of results obtained on the bathymetry, mine, and soil moisture programs are included. (Author)
