Research Abstract

Ultrasonic frequency modulation is a new knowledge which have been found by an applicant, Prof. Inoue. This phenomenon shows frequency modulation of ultrasonic as it passes inner boundaries in object. The aim of this study is to detect minute cracks and delaminations in object through the ultrasonic frequency modulation. An earlier detection of such cracks and delaminations is expected.
