A geometrical model based on an inverse ray-tracing approach to describe the Ronchi test for a concave spherical mirror is presented. In contrast to the conventional ray-tracing method, which refers to information unavailable in ronchigrams, the proposed model provides an explicit relation between the available information in the ronchigram and the parameters of the setup (radius of the sphere, position of the source, position and orientation of the observation, and grating planes). This allows for extracting the parameters of interest by a simple fitting procedure, as demonstrated by an application. The derived model exhibits new unexplored potential applications of the Ronchi test, establishing it as a very useful, simple, and universal tool for optical evaluation.
提出了一种基于反向光线追迹方法的几何模型，用于描述凹面球镜的朗奇测试。与传统光线追迹方法不同，传统方法涉及朗奇图中不可用的信息，而所提出的模型提供了朗奇图中可用信息与设置参数（球体半径、光源位置、观察位置和方向以及光栅平面）之间的明确关系。这使得通过简单的拟合程序就可以提取感兴趣的参数，如一个应用示例所示。推导得到的模型展示了朗奇测试新的未被探索的潜在应用，使其成为一种非常有用、简单且通用的光学评估工具。
