摘　　要：光学相控阵是激光雷达中实现非机械光束偏转的一种技术方案,针对现有光学相控阵存在的尺寸大、二维集成闲难等问题.提出了一种可实现二维光束偏转的新型二维光学相控阵反射镜。该反射镜采用易于集成的面阵结构.同时利用Gires-Tournois谐振腔在谐振波长附近的色散特性放大相移。仿真结果表明,该结构在谐振波长附近具有较高的相移效率,为实现二维光束偏转提供了一种新的解决方案。Optical phased array is a technical solution to realize non-mechanical beam steering in laser radar.In view of the large size and difficulty of two-dimensional integration of the existing optical phased arrays,we propose a new two-dimensional optical phased array reflector that can realize two-dimensional beam steering.The reflector adopts an easy-to-integrate area array structure and employs the dispersion characteristics of the Gires-Tournois resonant near the resonance wavelength to amplify the phase shift.Simulation results showed that the structure has a high phase shift efficiency near the resonance wavelength,and provides a new solution for realizing two-dimensional beam steering.
