Approximate Nature for the Imaging Matric Formula of Selfoc Lens
自聚焦透镜成象矩阵公式的近似性(英文)

This paper start off with ray equation, the imaging matric formula of Selfoc lens is derived particularly, approximate nature and applicable range of this formula can be seen from the derivation process, and this paper correct the view of some references to consider that the formula can be applied to the imaging of non-Gaussian optics.
