基于PLZT（铅镧锆钛酸盐）电光陶瓷的光学特性，利用横向电光效应，对三角形电极结构和光相控阵技术两种电光偏转器进行了详细研究。从理论上分析了偏转器的电光偏转特性和机理；实验测量了陶瓷片的相位调制、迟滞和电致损耗等光学特性；设计了一个系统的实验来验证理论结果。研究了温度对偏转板性能的影响。与两种结构的偏转器相比，光学相控阵技术具有更高的角度扫描分辨率，但偏转角相对较小。OCIS编码：（230.2090）光电器件；（160.2100）光电材料；（060.5060）相位调制。
Based on the optical characteristics of PLZT (Lead Lanthanum Zirconate Titanate) electro-optic ceramic, two kinds of electro-optical deflectors, triangular electrode structure and optical phased array technology, are studied in detail by using transverse electro-optic effect. Theoretically, the electro-optic deflection characteristics and mechanisms of the deflectors are analyzed; experimentally, the optical characteristics of ceramic wafer, such as the phase modulation, the hysteresis and the electro-induced loss characteristics, are measured; a systematic experiment is designed to verify the theoretical results. The effect of temperature on the performance of deflector is also investigated. Comparing with both structure's deflectors, the optical phased array technology has a higher angle scanning resolution, however, it has a relative small deflection angle.
