弛豫铁电体在非线性光学应用中很重要，因为即使在所谓的顺电态下也可以观察到非常大的明显的“电光克尔效应”。本文首先介绍了钙钛矿型多晶和单晶Pb（Zn_（1.3）Nb_（2.3））O_3，（Pb，La）（Zr，Ti）O_3和Pb（Mg_（1.3）Nb_（2.3））O_3·PbTiO_3的基本电光性质。然后，介绍了一种新型的用于图像投影仪的二维光阀阵列。采用流延成型技术制作了10 × 10像素的光闸阵列。板通电极和分离电极交替堆叠，以便通过连接分离电极的外部电极进行垂直寻址，并通过板通电极进行水平寻址。验证了其在高清晰度图像投影仪中应用的可行性。
Relaxor ferroelectrics are remarked in non-linear optic applications because an extraordinarily large apparent ‘electro-optic Kerr effect’ can be observed, even in the so-called paraelectric state. This paper describes the fundamental electro-optic properties of perovskite-type polycrystalline and single crystals, Pb(Zn1 3Nb2 3)O3, (Pb, La)(Zr, Ti)O3and Pb(Mg1 3Nb2 3)O3PbTiO3, firstly. Then, a new type of two-dimensional light valve array for an image projector is introduced. A light shutter array with 10 × 10 pixels was fabricated by a sophisticated tape casting technique. Plate-through and separate electrodes are stacked alternately so as to make vertical addressing by an external electrode connecting separate electrodes and horizontal addressing by a plate-through electrode. The applicative feasibility to a high definition image projector was verified.
