lens curvature 中文意思是什麼
lens curvature
解釋
透鏡曲率-
There are many different kinds of refractive surgery, but the principle is the same - changing the curvature of the cornea or lens to place the focus sharply back onto the retina
激光矯視種類繁多，然而，其原則如一，即改變角膜或晶體弧度，以令焦點明確地重落在視網膜上。 -
Compensating different stock removal of the tool in different lens areas is used to control the accuracy in pre - polishing process. then based on preston theory, corrective polishing with small - tools is optimized and the better removal function is obtained. also a parameter related the radius of curvature is introduced and determined to increase the polishing precision, which is improved by experiments
採用反饋補償的方法解決彈性模拋光對面形破壞的問題，以控制其拋光精度；運用preston的拋光原理，對小工具的工作方式和參數進行改進和優化，以改善其拋光精度和效率，並獲得了更優的特徵去除函數；提出了被拋光表面面形曲率半徑對工具特徵去除函數的影響，引入並確定一與非球面各處曲率半徑有關的面形調整因子來降低拋光后的面形誤差，並從實驗上獲得驗證。
