Vibration maps of capacitive micromachined ultrasonic transducers by laser interferometry

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2002
In this letter, a 1.8-mm x 1.8-mm capacitive micromachined ultrasonic transducer (CMUT) element is experimentally characterized by means of optical measurements. Optical displacement measurements provide information on the resonant behavior of the single membranes and also allow us to investigate the dispersion in the frequency spectrum of adjacent ...
