Matlab在几何光学仿真实验中的应用

Application of Matlab in simulated geometrical optics experiments

在工程光学教学中,为了使学生更好地理解球面光学成像系统与理想光学成像系统的区别,提出了用Matlab程序模拟球面光学系统成像过程的仿真实验,并编制了模拟程序.把系统结构参量r,d,n和物距L等代入到模拟程序中,就可以仿真成像系统的成像过程.仿真实验结果显示:理想光学成像系统的成像性质在球面光学成像系统中不存在,但可以通过设计优化使球面系统近似达到或者无限接近理想成像系统,理想成像系统的意义在于它的标准性.

When teaching of engineering optics,in order to enable students to better understand the difference between a spherical optical imaging system and an ideal optical imaging system,a simulation experiment using Matlab was presented.Structural parameters r,d,nand L(object distance)of an optical system were substituted into emulation programs,the imaging process of a spherical optical system could be emulated.The simulation results showed that the imaging properties of ideal optical imaging system did not exist in spherical optical imaging systems,however,spherical systems could approximately approach or infinitely close to the ideal imaging system by optimizing the design of the structure.The worth of an ideal imaging system lied in its standards.
