發(fā)布時間:2019-01-03 17:15
【摘要】:為了滿足人們對超廣角、大視野的取景需求,運用光學軟件CODE V和Zemax設計了一個結(jié)構緊湊的用于運動數(shù)碼攝像機的魚眼鏡頭光學系統(tǒng).該鏡頭由5片玻璃鏡片和3片塑膠非球面鏡片組成.設計結(jié)果表明,鏡頭F數(shù)為2.2,視場角為240°,系統(tǒng)總長度為23mm,半像高為2.35mm,在1/2奈奎斯特頻率(178lp/mm)處所有視場均大于0.15,可以實現(xiàn)高清全景監(jiān)控.投影檢測結(jié)果顯示,該魚眼鏡頭產(chǎn)品的性能滿足要求.
[Abstract]:In order to meet the demand of wide angle and large field of vision, a compact optical system of fish-eye lens for moving digital camera is designed by using optical software CODE V and Zemax. The lens consists of 5 glass lenses and 3 plastic aspherical lenses. The design results show that the lens F number is 2.2, the field angle is 240 擄, the total length of the system is 23mm, the half-image height is 2.35mm, and all the field of view at 1 / 2 Nyquist frequency (178lp/mm) is greater than 0.15, which can realize the high-definition panoramic monitoring. The projection detection results show that the performance of the fish-eye lens meets the requirements.
