PLZTのミクロ構造と電気光学効果

抄録

Optical shutter array of an electrophotographic page printer was made from HIP'ed PLZT ceramics. There was a marked variation of the light intensity among individual apertures of the shutter array when the ceramic having coarse grains was used. This is caused by the inhomogeneous distribution of the portion having different birefringence at a given electric field direction. The portion has an approximate diameter of a grain. So the optical shutter array should be made of PLZT ceramics with fine grain size and high optical transmittance.
