Direct visualization of ultrasonic power distribution using mechanoluminescent film.
In this research, a technique for measuring ultrasonic power with a mechanoluminescent (ML) sensing film was developed. A linear relationship was observed between the ultrasonic power and the ML intensity induced by ultrasonic vibration, indicating that ultrasonic power can be evaluated by measuring ML intensity. In addition, the ultrasonic power distribution on the surface of a transducer was visualized by recording ML images with a charge-coupled device camera.
