| 摘 要： | 为了满足隐秘型ＣＣＤ摄像光学系统的广角视场、长工作距离、小空间尺寸、隐蔽性能好、成像质量优良等特殊要求。提出一种以同心透镜作为负组，置孔径光阑于镜头前方的新型反远摄结构。对其设计思想、像差特点进行了分析，并给出了ｆ′＝３６ｍｍ，２ω＝８０°，ｌＦ′／ｆ′＝１１的隐秘型ＣＣＤ微摄像镜头的像差和传函计算曲线

| Abstract: | A new retro telephoto lens design for concealed color CCD video imaging, in which a concentric lens is used as the negative element and its aperture stop is located in the front of lens, has been presented in order to meet the requirements of wide field of view in a small package, long working distance and highly hidden ability. The design considerations and the characteristics of aberrations is discussed. A useful design result with f′= 3 6mm ,2ω=80°, l F ′/f′=1 1 is provided. The aberration curves and calculated MTF of the micro retro telephoto lens are also given. |
