【摘要】：为了满足人们对超广角、大视野的取景需求,运用光学软件CODE V和Zemax设计了一个结构紧凑的用于运动数码摄像机的鱼眼镜头光学系统.该镜头由5片玻璃镜片和3片塑胶非球面镜片组成.设计结果表明,镜头F数为2.2,视场角为240°,系统总长度为23mm,半像高为2.35mm,在1/2奈奎斯特频率(178lp/mm)处所有视场均大于0.15,可以实现高清全景监控.投影检测结果显示,该鱼眼镜头产品的性能满足要求.
[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 掳, 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.
