聚焦品質一直是光學發展中需要改善的對象, 本論文希望利用數值方法設計出可解決聚焦品質的透鏡。先假設平行光入射一固定位置的凹面鏡, 一次折射後再經過一非球面鏡二次折射後會匯聚於一點, 用數學推導出此非球面鏡會滿足兩條常微分方程式。我們利用數值分析RungeKutta四階求此常微分方程的數值解, 而造出一良好聚焦透鏡。因為光線最後出射時的折射線和光軸的夾角可以寫成y 的多項式, 所造出的良好聚焦透鏡在平行光入射時, y 的三次項係數會近似1/3。再傾斜入射光角度, 找出y 的常數項、一次項、二次項係數為何, 進而設計出有較好聚焦品質的透鏡。
Focusing equality always needs to be improved in optics . In this thesis , we hope to design lens for solving focusing equality by numerical analysis . Assume that the light which parallels optical axis is incident a concave lens which is fixed . After the first time refraction , passing through an aspherical lens and the second time refraction , the light will focus in a spot . This aspherical lens will satisfy two Ordinary Differential Equation(ODE) . We use Runge Kutta fourth-order method to find out the numerical solution for those two ODE , and make a perfect focusing lens . Because the angle of the refracted ray and the optical axis can represents by y’s polynomial. Perfect lens’s y’s coefficient of degree three is approximate 1/3 . Adding angel step by step , we find y’s coefficient of scalar , degree of one , degree of two , and then design a better focusing equality lens .
