The application of Fermat's principle for imaging anisotropic and inhomogeneous media with application to austenitic steel weld inspection

Ultrasonic inspection in anisotropic and inhomogeneous media has long presented a challenge because of the complex steering of ultrasonic paths. An approach is presented in which the true geometry of a previously used austenitic steel weld model is distorted so that, from one viewing location, all u...
