Abstract
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.
