• In order to evaluate the contribution of the non-180 °domain reorientation in the electric-field-induced strain of PZT ceramics, a Mach-Zehnder interferometer was constructed and the electric-field-strain of PZT ceramics was measured as a function of frequency. The piezoelectric constant of PZT ceramics determined by the interferometer well agreed with that determined by the resonance method. The resolution of the interferometer was about 0.01nm. The electric-field-induced strain curve showed a hysteresis under high electric fields and low frequencies. The apparent piezoelectric constant determined form the electric-field-induced strain increased with decreasing frequency under high electric fields. These behaviors were interpreted as the effect of non-180°domain reorientation.
