Abstract
Example systems and methods for nondestructive ultrasonic testing are provided. One example system includes at least one air-coupled ultrasonic transducer configured to emit primary ultrasound waves that interfere with each other. The primary ultrasound waves include fundamental frequency components that are multiples of each other and emitted simultaneously in locked phase. Further, the interference of the primary ultrasound waves generates a plurality of frequency harmonics in the air. The system also includes at least one receiver configured to receive ultrasonic waves emitted from an object under test.
