The measurement of the ultrasonic output power emission from transducers is a very important subject because strong ultrasonic power may be harmful to human health during medical diagnosis and therapy. Conventional techniques for measuring ultrasonic power such as radiation force balance method and calorimetry method provides no information on power distribution, laser interferometry method is very expensive and time-consuming. We have demonstrated in previous research that the mechanoluminescent (ML) film can be used as a sensor for visualizing the ultrasonic power distribution of a transducer with a frequency of 20 MHz. In this research, the ultrasonic power distribution of a transducer with a frequency of 6 MHz was also visualized. The results suggest that this method can be used for visualizing the ultrasonic power distribution of transducers with a wide range of frequency.
