Thickness Measurement of a Curved Multilayered Polymer System by Using an Ultrasonic Pulse-Echo Method

The effect of the curvature on the measurement of thickness of each layer of curved multilayered polymer by using an ultrasonic pulse-echo method was investigated. The real location of the focus of an acoustic beam in a curved, layered structure was calculated by an optical-ray model. Experimental r...
