- 論文の詳細を見る
A method for measuring the mode shapes of quartz crystal resonators using an electrostatic microphone is described. In this method the resonator driving current is strongly modulated, and a needle connected to the microphone picks up the modulation signal on the resonator surface. The vibrational patterns are obtained by mapping the detected modulation signals on the resonator surfaces. The experiments were carried out using AT-cut rectangular quartz plates and the results were compared with those from the calculations.
