Study on Precise Control of PZT Ceramics of Rich Power Piezoelectric

Abstract

The basic principle,characteristics and driving means of the piezoelectric ceramic were discused in this paper,and the open loop measure method of piezoelectric ceramic's characteristics was designed.In the course of experiments,the stability of optical table should be further adjusted.The photoelectricity receiving amplifier was designed,and the piezoelectric charactoristics of piezoelectric ceramic were analysed in detail by confocal cavity interference version.
