An attempt is made to use the filled function as the modified function approach to apply global optimization to optical thin film problems. it is proved successful when applied to problems such as antireflection coatings and beam spliters. meanwhile, it is also found that when the number of layers is fixed those local minima with less total optical thickness appear to be better. in the realization. needle method are made to explore the impact of local optimization methods used, parameter of these methods, the starting design, the search accuracy of function and the methods of thickness growth
從理論分析來看，由於光學薄膜的特性是由在入射介質那一側的等效導納所確定的， needle方法把等效導納作為狀態變量，把每一層的折射率作為控制變量，運用最優控制的原理計算出在薄膜內部每一個厚度對應的點上折射率改變所引起的評價函數的改變，由此選取改變折射率后評價函數變化最大（評價函數變小）的那一點進行插入。
