用于视网膜成像的眼底相机由两部分组成，其一是具有正调焦镜的成像光路，另一是环形的柯勒照明光路。本文中分析了一种基于内调焦方式的眼底相机光学结构，提出了相应的调焦方程和光瞳衔接方程，并根据这两组方程计算了眼底相机的结构。所设计的成像光路具有紧凑的初始结构，总长约为123mm。调焦的范围可达-10D～10D，调焦镜的移动量曲线接近于线性变化，每1D屈光度对应的调焦镜移动量大于亚毫米量级。

The fundus camera used in imaging retina includes two parts: fundus imaging path with a positive focusing lens and annular Kohler illuminating path. We present a pupil joint equation and a focus equation based on the internal focusing manner to analyze its configuration. Using these equations, the configuration of the camera is given in detail. The design result of the fundus imaging path shows compact initial configuration at a total length of about 123 mm. The focusing range is -10-10 diopter, and the movement of the focusing lens is nearly linear at displacement of more than a sub-millimeter per diopter.
