摘　　要：以生物视觉成像和目标识别为研究背景,深入研究了光学复眼的结构与拼接以及基于光纤耦合的光信号接收成像技术,并设计了一种可应用于凝视激光雷达的新型光学复眼接收系统。通过模仿昆虫复眼结构形式,该系统由16个透镜阵列构成,全视场角为2°。利用Zemax软件完成了光学系统设计,结合光纤耦合技术接收光信号,对复眼探测结果进行了实验研究和分析。结果表明,该接收系统能够准确地反映探测目标轮廓,探测距离可达200m以上,在实验室获得了20frame/s的距离图像,像点点阵间距为1.72m×1.72m。实验结果验证了该接收系统的合理性,表明该系统可以满足导弹末制导使用或是低空飞行器下视地形匹配。On the basis of biological visual systems and object recognition technologies,several key technologies of artificial compound eyes,including its structure,splicing,fiber coupling and optical signal receiving technique were studied and a bionic compound eye receiving system was designed for staring laser radars.By imitating the structures and shapes of compound eyes of insects,the system consists of 16 lens arrays,and its whole field angle is 2 °.The optical system was designed by the Zemax software and optical signals were received by fiber coupling technology.The detection results were studied experimentally,and it shows that this receiving system can well reflect the contour of a detecting target,and the detection range is more than 200 m.On the experimental setup,a range image with 20 frames is obtained,and the pixel space is 1.72 m×1.72 m.Obtained results verify the feasibility of proposed system and indicate that the system can be used in the missile end-guiding and the topographic matching of aerocrafts in low altitudes.
