传统的机械式激光雷达成本高、可靠性低,难以满足自动驾驶大规模推广的需求,激光雷达迫切需要向固态化方向发展。光学相控阵(OPA)技术通过控制阵列中阵元光束相位来调整输出光束方向,其具备视场宽、功耗低等性能,高性能的光学相控阵有助于实现激光雷达的全固态化并获得较高可靠性。介绍并总结了光学相控阵技术的基本工作原理及主要实现方式,分别论述了光波导相控阵、液晶相控阵、微机电系统(MEMS)相控阵的技术现状及发展侧重点,重点梳理了相关专利申请情况并介绍了具有代表性的专利,最后展望了其未来的发展趋势。
Abstract：Traditional mechanical LiD AR is high in cost and low in reliability,which cannot meet the requirements of popularization of unmanned driving and urgently needs to develop to solidstate.Optical phased array(OPA)is a technique that adjusts the direction of the output beam by controlling the phase of the array beam,which has wide field of view and low power consumption.High-performance optical phased array can help LiD AR achieves all-solid-state and higher reliability.The basic working principle and the main implementation methods of optical phased array technology are introduced and summerized.The technical status and development focus of three main ways of optical phased array,namely optical waveguide phased array,liquid crystal phased array and micro-electromechanical system(MEMS)phased array,are discussed.The relative patent applications are focused and the analyzed and representative patents are introduced.Finally,the future development trend is prospected.
