Electric and Optical Properties of PLZT Ceramic Shutter Array

This paper is concerned with a light-shutter array of PLZT transparent ceramics utilizing newly-developed electrode structure. Relationships between shutter characteristics and electrostrictive effect of the PLZT are investigated. The electrode structure plays significant roles on the reliability of the shutter characteristics. Thus, by introducing a double layer electrode structure coated with resin, the highly stable light-shutter array is obtained to a long time drive. Furthermore, small temperature dependent shutter array can be also realized by controlling each width of the electrode and light-shutter aperture.
