【摘要】 随着电子、信息、材料、光学、机械等学科的飞速发展,基于非成像光学的激光探测技术近年来受到人们越来越多的关注。高准确度和非接触测量的特性使激光探测光学系统广泛应用于激光测距、激光雷达和激光制导等领域。本文根据四象限探测器原理以及传像束光纤的特点,提出了一种新型的分布式孔径半主动激光探测系统来获得目标的角度信息。该系统由四个满足像方远心光路的光学系统、一个4×1的传像束光纤、一个探测器组成。通过搭建系统原理样机,定量测量半主动激光探测系统的线性区范围及测角误差。实验结果表明,系统具有±12°的线性视场,测量值与线性区的理想曲线相接近,满足光学系统的设计技术指标。

【Abstract】 With the rapid development of electronics,information,materials,optics,and mechanical disciplines,non-imaging optics laser detection technology has received more and more attention in recent years.High accuracy and non-contact measurement characteristics make laser detection optical systems widely used in laser ranging,laser radar,and laser guidance.In this paper,a novel distributed aperture semi-active laser detection system is proposed to obtain the target angle information according to the principle of the four-quadrant detector and the characteristics of the image beam fiber.The system consists of four optical systems that meet the telecentric light path of the image square,a 4×1 beam fiber,and a detector.By setting up a system prototype,quantitatively measure the linear range of the semi-active laser detection system and the measurement error.The experimental results show that the system has a linear field of view of±12°,and the measured value is close to the ideal curve of the linear region,which satisfies the design specifications of the optical system.
