摘　　要：利用短程透镜 (GL)焦点、焦平面、焦距、主点、主平面等的表达式 ,根据短程透镜在大口径范围内理想聚焦 ,主平面为以焦点为圆心、以焦距为半径、在原点相切的两个圆弧等性质 ,推导出了短程透镜物像关系的作图法求取原则 .这一原则不仅可以在近轴区成立 ,而且在远轴区亦成立 ,弥补了以往短程透镜仅有针对特定共轭物像点的传递关系的缺陷 ,大大方便了短程透镜在所需系统中的应用 .分析认为 。According to the obtained characteristics of focal points and principal planes, using the expressions of focal point, focal plane, focal length, principal point, and principal plane of geodesic lenses (GL), the geometry graphic imaging formation principles of geodesic lenses are developed to get the object-image-relation of geodesic lenses. These rules fit for both paraxial rays and off-axis rays. Therefore, the object-image-correlation of parallel light, on-axis points, off-axis points and object AB can be obtained freely by graphic method. They are profitable for designing and calculating the systems containing GL.
