Underwater imaging system

摘要

Acoustic imaging system wherein signals from a target of interest impinge upon a set of receiving transducers. The transducer signals are processed and form the input signals to a transparent delay line through which is projected coherent light from a laser. Suitable optics and detectors are positioned relative to the projected laser beam so as to produce an output signal that is applied to a CRT to display a range profile or contour map of the target area.
