摘要
光学相控阵通过对阵列天线相位的调节以改变发射波束的波前,从而实现对发射波束的控制。光学相控阵技术在激光雷达、激光通信、高亮度激光生成、合成孔径探测等领域极具应用潜力。本文综述了液晶相控阵、微机电系统相控阵和光波导相控阵的研究进展以及优缺点,并对激光雷达中的光波导相控阵技术进行了深入思考,提出了光波导相控阵技术的突破方向。
The optical phased array controls the emission beam by adjusting the phase of the array antenna to change the wavefront,thus achieving control over the emission beam.Optical phased array technology has great potential applications in areas such as laser radar,laser communication,high-brightness laser generation,and synthetic aperture detection.This article reviews the research progress,advantages,and disadvantages of liquid crystal phased arrays,micro-electro-mechanical system phased arrays,and optical waveguide phased arrays.It also delves into the optical waveguide phased array technology in laser radar,proposing breakthrough directions for this technology.
