Total Internal Reflection Ultrasonic Sensor for Detection of Subsurface Flaws: Proof of Concept

Abstract

This report results from a contract tasking National Taras Shevchenko University of Kyiv as follows: The objective of the proposed study is to provide an experimental validation of the described concept. To achieve this objective it is necessary to solve two main tasks: (1) to analyze theoretically total internal reflection of an ultrasonic wave at a proper solid-solid interface and then to offer a sensor design based on the proposed technique; (2) to develop a test sample of the sensor, to fabricate it and examine its sensitivity to an artificial flaw in the tested object.
