    Abstract: A protective dome (14) is provided for a zoom telescope (12) which is located therein. Telescope (12) can be used as an attachment to a prime imaging system (22) such as a FLIR (forward looking infrared). The dome (14) is mounted so that its center of curvature (16) is inboard of the outer skin (18) of the aircraft in order to reduce aerodynamic drag. The objective lens (24) of the telescope (12) is decentered with respect to a common axis (29) and the lenses of the zoom lens group (26) are tilted with respect to the common axis (29) to compensate for aberrations introduced by the decentered dome (14).

    Abstract translation: 为位于其中的变焦望远镜(12)提供保护圆顶(14)。 望远镜(12)可以用作主要成像系统(22)的附件,例如FLIR(前瞻性红外线)。 安装圆顶(14)使其曲率中心(16)在飞行器的外皮(18)的内侧,以便减少气动阻力。 望远镜(12)的物镜(24)相对于公共轴线(29)偏心,并且变焦透镜组(26)的透镜相对于公共轴线(29)倾斜以补偿引入的像差 通过偏心圆顶(14)。
