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.In order to meet the requirement of the ultra-wide angle and large view landscape, a compact structure fisheye lens system for the sport digital video is designed with the optical system design software CODE V and Zemax. The lens comprises 5 pieces of glass lenses and 3 pieces of plastic aspheric lens. The design result shows that the F-number is 2.2, field angle is 240°, the total length of the system is 23 mm, the half image height is 2.35 mm, and all of the field of view at half of Nyquist frequency （178 Lp/mm） are more than 0.15. The lens achieve high-resolution panoramic monitor. The projection detection result shows that the performance of the fisheye lens can meet the requirements.
