Abstract

An ultrasonic inspection element and method are provided for improved ultrasonic inspection of curved entry surface parts. The transducer element may be spherically focused, or have a flat surface. The transducer/mirror element combination is used to inspect through a concave or convex surface. A mirror element shapes the sound beam relative to the shape of the curved surface of the part being inspected. Curvature of the mirror is adjusted with a screw, rod, voltage modulator, or other suitable adjustment mechanism. An alternative mechanism includes multiple "quick disconnect" interchangeable curved mirror elements.
