Abstract:
A series of experiments to determine the ability of laser vibrometers to receive and process echoes from the water surface are described. Imaging of the bottom and objects lying on the bottom is attempted. The excitation is accomplished by a submerged acoustic source operating near 10 kHz. The degradation of the image is quantified as a function of wave height. Experiment results are reported. [Work supported by Coastal Systems Station under Internal Research funding.]
