一种摄像机成像物镜及其机载光电式头盔瞄准系统
Abstract:
本发明涉及一种摄像机成像物镜，其应用于机载光电式头盔瞄准系统中。所述摄像机成像物镜从物侧到成像面依次包括光栏、像方焦点位于成像面一侧的光焦度为正的第一透镜、以及具有曲率很大的凹面朝向成像面一侧的光焦度为负的弯月型第二透镜，所述第一透镜和所述第二透镜均至少有一面为非球面，且满足条件式：其中，f是整个所述摄像机成像物镜的焦距；f1是所述第一透镜的焦距；f2是所述第二透镜的焦距。所述摄像机成像物镜能校正所述机载光电式头盔瞄准系统的球差和彗差。本发明还涉及一种具有所述摄像机成像物镜的机载光电式头盔瞄准系统。
Abstract(English):

The invention relates to a video camera imaging objective lens. The video camera imaging objective lens is applied in an airborne photoelectric helmet aiming system. From an object side to an imaging surface, the video camera imaging objective lens comprises a diaphragm, a first lens and a crescent-shaped second lens in turn, wherein the first lens has a rear focus of which focal power on one side of the imaging surface is positive; the crescent-shaped second lens has a concave surface which has very high curvature, and the focal power facing one side of the imaging surface is negative; at least one surface of both the first lens and the second lens is a non-spherical surface and is in accordance with conditional formula: 1.3
