| Abstract(in English) | A novel measurement method of displacement using ultrasonic waves having a pair of frequencies(ƒ_0andƒ_1) generated by a piezoelectric device is described. The displacement is estimated from the detected phases of ultrasonic received signals and the detectable displacement range is extended by neighboring the frequency interval(ƒ_0-ƒ_1). The displacement measurements based on our method were carried out using ultrasonic waves of 5 MHz in water. Although a measurement range using the single frequency measurements is limited to a half of wavelength or less, the extension of the measurement range by 500 times of wavelength is accomplished by our method. |
