Abstract
A display system for use with a well logging tool of the type that scans a borehole wall by rotating an acoustical transducer while emitting and receiving acoustic energy. The received acoustic or information signals are received and recorded for later use. In addition, both the amplitude and time-of-flight of the information signals are digitized and passed to a computer that controls a television display and cathode ray tube. The amplitude is displayed on the television screen while the time-of-flight is displayed on the cathode ray tube as a caliper log.
