Abstract

As the electrostrictive actuator for optic control, PZN-BT-PT ceramics were investigated for the influences of sintering conditions on the structural, electrostrictive properties and the optical properties of Fabry-perot Interferometer using eletrostrictive ceramics. The specimen SS15T, sintered 1hr at 1150$^{\circ}C$, is sutible for eletrostrictive actuator because its piezoelectric constants(dS131T) and strain(XS131T) at dc 10kV/cm had the higest value of 175${\times}$10S0-12TC/N, -255${\times}$10S0-6TΔl/l respectively. As the dc electric field increased, the interference effect of Fabry-Perot Interferometer was increased. The most intense interference fringe and the maximum power of 160${\mu}$W were observed at dc 6kV/cm. Thus it was considered that specimen SS15T could be used as the electrostrictive actuator for optic control.
