本文从光线方程出发,对自聚焦透镜成像矩阵公式做了详细推导,由推导过程即可看出该公式的近似性及其应用范围,纠正了一些文献上认为该公式可应用于非高斯光学成像的看法。

Based on the ray equation, imaging matric formula of the selfoc lens is derived is detail in this paper. Approximate property and applicable range of this formula can be seen from the derivation process, and the view of considering the formula applicable to the imaging of non-Gaussian optics should be corrected.
