Abstract
A technique to detect underwater acoustic signals by utilizing the resultant surface perturbations is discussed. These perturbations result in an amplitude modulation effect on a laser beam reflected by the water surface. A theory to explain this phenomenon is discussed. A detection system based on this theory was developed. Laboratory investigations were conducted to evaluate the characteristics of the system. Preliminary results indicate that detection based on this technique is possible
