| Summary: | 碩士 === 國立成功大學 === 數學系應用數學碩博士班 === 98 === In this paper, we discuss how to use the Ordinary Differential Equation to design the perfect focus lens, and then use the numerical method of Runge-Kutta 4 to compute the perfect focus lens. Finally, we can also solve the ordinary differential equation to find the exact solution.
Traditionally, we use the Paraxial ray-tracing to simulate the optic systems on Paraxial Optics, and this method will result in some inaccuracy. Therefore, we have to use the strict ray-tracing to simulate the optic systems by the Visual C++. We also use different ray and different lens to compare their aberration.
Finally, we combine the different lens, and we also have to take account of the optic systems’ thickness and the refractive index of the medium. Afterward we use the program to find the fitting focus for the optic systems.
