Generalized ray theory and its application to long-distance ultrasonic testing
Abstract
The theory of generalized rays is investigated for use in modeling the detection of vertical defects in plates using long-distance ultrasonic testing (LDUT). The theory can be extended to analytically verifying synthetic aperture focusing technique (SAFT) generated images of defects from experimental data. Used together, generalized ray theory and long-distance ultrsonic testing allow crack detection without knowledge from previous measurements.
