| Abstract: | Measuring methods of the sound field intensity of power ultrasound are summarized. According to different effects of ultrasound field being measured,the methods can be divided into the method of mechanical effect,the method of thermal effect,the method of chemical effect,and the method of optical effect. And the spatial resolution,bandwidth,sensitivity,pressure range and applicability of some methods are described. |
