- W3108195111 abstract "为测量光线入射角度，设计了一种基于锥形透镜的新型光线入射角度测量系统。利用光阑、锥形透镜和图像接收装置，获取待测光线通过光阑射入锥形透镜后经过多次的折射和反射，在图像接收装置上得到的复杂光斑图像，通过图像处理得到光斑图像特征信息，进而求解光线入射角度。采用锥形透镜的测量方案，角度测量范围可达80°，精度最高可达 (1×10<sup>−4</sup>)″。该方案结构简单、体积小且不需要进行繁琐的安装调试。与现有的单光点测量等方法相比，该方案中锥形透镜具有角度放大作用，可大幅度提高测量精度且具有大视场；图像传感器像素分辨率对测量结果影响较小，系统光通量大，容易获得较高的信噪比。" @default.
