This paper provides a kind of ultrasonic measurement for object vibration. Through the use of LabVIEW and ultrasonic sensors, the whole system would be simple and cost would be much lower. And then some key problems have been solved, such as the nearby wavelet produced by the ultrasonic sensor, the background noise and also the dead zone for measurement. So the measurement would be more accuracy. As a result test, it recorded a curve produced by a kind of damp vibration which shows that the system can meet the demand for application.
