摘　　要： 与传统曲面复眼结构不同,提出了在曲面基底上设计非均一微透镜阵列的构想。整个透镜阵列呈环状对称分布,沿径向排列的各级透镜其焦距由所处位置决定,与基底到光探测阵列的距离相吻合。根据几何光学成像原理计算了各级透镜的设计参数并通过光线追迹加以验证。仿真结果表明,这种设计可对全视场在光探测阵列上聚焦,解决了传统曲面复眼边缘视场成像质量急剧下降的问题。同时还论证了采用光刻胶热熔法在曲面基底上制作非均一微透镜阵列的可行性。 Different from the conventional spherical compound eye imaging system, a novel optical design structure was proposed that the non-homogeneous microlens array was fabricated on the spherical substrate. The whole array was arranged as symmetrical circle pattern, and the focal length of microlenses arranged along the radius direction was decided by its position and equal to the distance between substrate and photo-detector. According to the imaging theory of geometrical optics, the design parameters of microlens array were computed and verified by ray tracing procedure. From the simulated results, we can get the conclusion that the optimal design structure of single-layer spherical compound eye can focus the whole obviously. Moreover, field of vision the fabrication on the photo-detector and improve the imaging quality of the edge field of vision technology of non-homogeneous microlens array on spherical substrate is discussed.
