  • 摘要: 仿生复眼系统是一种多子眼拼接的大视场高分辨率成像系统,由一级同心物镜和二级子眼镜头阵列组成。为实现大视场无缝隙拼接成像,必须严格保证所有子眼镜头的光轴与同心物镜球心的对准误差在光学设计允许的公差范围内。首先,基于PSM(point source microscope)定位仪的自准直原理确定PSM的基准参考零位,然后通过转接器将PSM分别固定在所有子眼镜头安装孔中,计算经同心物镜反射后像点质心位置与子眼安装孔轴线对准误差的几何关系式,最后用Lighttools软件仿真检测光路并对所有安装孔对准误差进行检测。实验结果表明:所有安装孔轴线与同心物镜球心的对准误差均小于30 μm。满足光学设计中子眼镜头光轴与同心物镜球心对准误差小于50 μm的公差要求,从而保证了仿生复眼成像系统大视场高分辨率无缝拼接影像的获取。
