摘　　要：提出了由扫描法布里-珀罗干涉法测量微小形变的方法,设计了一种基于激光扫描法布里-珀罗干涉原理的压电常数d_(31)测试系统.文中给出了测量原理、测量装置及陶瓷样本的测量结果,并与用IEEE标准测量方法的测量结果进行了对比,测试结果表明两者相差很小.Based on a method of measuring tiny deformation by scanning Fabry-Perot interferometer, a testing system for piezoelectric constants is proposed. In this paper, we discuss the measuring principle, the measuring apparatus, and experimental results for a typical example. The piezoelectric constants obtained by this method are in very good agreement with the experiment data by the IEEE method.
