Abstract: Time difference of arrival (TDOA) and direction of arrival (DOA) are, respectively, applied to detect partial discharge (PD) target with ultrasonic signal. The reason why these two methods ...
Abstract: Laser Doppler Vibrometers (LDVs) are the most common optical characterization equipment for CMUTs since LDVs characterize both static and dynamic CMUTs in terms of static deflection and ...
