| Abstract: | The ceramics piezoelectricity characteristics whith includes vibrational swing and period of driving signal have been observed and measured with the method of laser interferometry. Based on the counter and tuner of single chip Micyoco, the driving time, the amount of moved interferometry stripe and the displacement of ceramics piezoelectricity have been measured and displayed on digital tube electrocircuit. |
