Title: Retroreflector for ultrasonic inspection

Abstract: A system for ultrasonic inspection of a structure includes a transducer located at a first surface of the structure to transmit an ultrasonic signal from the transducer through the first surface to a second surface of the structure located substantially opposite the first surface. A plurality of retroreflector elements are located at the second surface to reflect the ultrasonic signal back toward the transducer. A method of ultrasonic inspection of a structure includes transmitting an ultrasonic signal from a transducer located at a first surface of the structure toward a second surface of the structure located substantially opposite the first surface. The ultrasonic signal is reflected back toward the transducer via a plurality of retroreflector elements disposed at the second surface.
