Abstract: 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 rulesfit 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.
