摘要(中) 汽車工業的發展,帶來了便利;因此安全性相對重要,有鑑於此,本論文利用三片塑膠鏡片設計全視角達146 度的超廣角車用鏡頭,首先選擇美國專利7304808B2 做為起始值,進行初階規格計算、鏡頭參數優化。
其中,考慮塑膠鏡片製造的限制,加入對高次非球面係數的控制來避免極值、模仁入刀角度過大的問題產生,找出高次非球面係數對深度變化的規則,最後進行公差分析,完成設計。
摘要(英) The development of automobile industry is convenient for the life; therefore the vehicle safety is an important issue when the vehicles were drove on the road. For the reason, we proposed the ultra-wide angle lens which has 146 degree of field of view (FOV) to be designed by three plastic lenses in this paper. First, we chose the initial value from the United States patent of No. 7730406B2. Second, the basic specification was obtained after our calculating. Final, we optimized the coefficients of lenses in the program.
We dominated the high order coefficients of aspheric lenses and found the regularity in high order coefficients and SAG of aspheric lenses to avoid the restrictions on the plastic lenses making, such as lenses diameter and mold of cutting angle. In the end, the design was accomplished after tolerance analysis.
