Sonic system for locating objects in the bottom of a borehole
Patent
·
OSTI ID:5517826
A method and apparatus are described for obtaining a visual representation of submerged objects, such as junk in the bottom of a borehole. A narrow beam of repetitive sonic pulses, with a peak frequency of about 1 mc per sec, is directed toward the submerged object in a zigzag scanning raster. Sonic reflections from the submerged object are detected and are utilized to intensity modulate the electron beam of an oscilloscope which is deflected in a scanning raster related to that of the sonic beam. Thus, there is produced on the face of the oscilloscope an intensity modulated display of the submerged object. (7 claims)
