摘要
PROBLEM TO BE SOLVED: To provide an ultrasonic thickness measurement method and an ultrasonic thickness measurement system capable of easily measuring a thickness after a second layer of a multi-layered structure material in a case where ultrasonic echo of a measurement object layer is overlapped with multiple reflection echo of a former layer.;SOLUTION: An ultrasonic thickness measurement method for measuring a thickness of each layer of a multi-layered structure material in which at least two or more different materials are laminated with an ultrasonic echo method, measures the thickness after the second layer by actively changing the temperature of the multi-layered structure material and utilizing the fact that the way of overlapping of the measurement object layer on the multiple reflection echo of the former layer changes due to the temperature.;COPYRIGHT: (C)2015,JPO&INPIT
