Outline of Final Research Achievements

A new ultrasonic imaging system using vibration velocity is described. Uniform Surface Vibration (USV) is obtained when the piezoelectric transducer is driven by the constant voltage source. Imaging of sample placed on the piezoelectric transducer detected with the Laser Doppler vibrometer is suggested. Vibration velocity waveform which is analogous to that of driving voltage pulse in time are confirmed both from the analysis of transmission line model and experiments. Experiment of imaging having the character “U.S” on the aluminum plate are imaged. As the results, the suggested system would become a useful tool for an ultrasonic imaging in air. Moreover, this method was applied in the low S/N condition imaging, Barker coded pulse was useful in the high absoption sample imaging.
