摘　　要：运用矩阵运算方法,得到一个与自聚焦透镜完全等价的单薄透镜光学系统。这个等价光学系统,仅由一个正薄透镜和两个完全相同的光学间隔组成。在近轴近似条件下,它可以替代自聚焦透镜,从而大大简化包含复杂自聚焦透镜的光电系统的光学分析。利用这个等效光学系统,对所有节距的自聚焦透镜的成像特性进行了研究,阐明了各个节距的自聚焦透镜的物像关系。并在此基础上讨论了该等效系统在光纤准直、复印机光学系统以及光纤耦合器里的应用。A simple thin lens optical system fully equal to selfoc lens is got by using the method of matrix optics.This equivalent optical system is composed of a positive thin lens and two same optical intervals.Under the condition of paraxial approximation,the system can substitute a selfoc lens to simplify the optical analysis of an optoelectronic system containing complex selfoc lenses.Imaging properties of a selfoc lens at various lengths are studied and the object-image relation of a selfoc lens at various lengths is presented by using this equivalent optical system.Based on this,the application of the equivalent optical system,such as fiber collimation,optical system of photocopy machine,and fiber optic coupler,is discussed.
