Abstract
A detecting method on quantity and oil existence in a model tank using ultrasonic pulse echo method have been assuming the remained oil inside sunken ships C scope which is one of the method of the pulse-echo method was used for the construction of image. This experiment showed that the measurement of the remained oil inside the sunken ship was possible using ultrasomcpulse echo. The goal of thisreseamh will be the establishment of this technology to can measure remained oil inside sunken ships quantitatively and three-dimensionally by tomography-method using many measuring points.
