Abstract: Usage of light diffraction tomography to measure the acoustic field of micromachined ultrasonic transducers (MUT) in cases in which standard methods like hydrophone and microphone measurements fail is demonstrated. The results reveal that the air-coupled MUTs in the frequency range of about 1MHz as well as the extreme near field of a miniaturized continuous wave 10 MHz water-loaded transducer were successfully characterized with light diffraction tomography.
