基于掺镧锆钛酸铅(PLZT)电光陶瓷材料的光学特性,提出了一种具有上下电极结构的光学相控阵高速光束扫描器。在理论上,分析了具有这种结构的光学相控阵的光束电光偏转特性和机制;在实验上,分析了掺镧锆钛酸铅材料的相位调制特性和损耗特性,制作了相关的光学相控阵器件,并构建了相应的测试系统,获得了光束在空间的角度偏转,与理论分析结果相符。 Based on the optical properties of lanthanum-doped lead zirconate titanate (PLZT) electro-optic ceramic material, an optical phased array high-speed beam scanner with upper and lower electrode structures was proposed. In theory, the optical electro-optic deflection characteristics and mechanism of the optical phased array with this structure are analyzed. The phase modulation and loss characteristics of the doped lanthanum-doped lead zirconate titanate material are analyzed experimentally, and the related optical phase The device is controlled and the corresponding test system is constructed. The angular deflection of the beam in space is obtained, which is consistent with the theoretical analysis.
