本文所介绍的一种小型彩色电视摄象光学系统,用在宇宙飞船驾驶舱摄象机装置上。该光学系统的一个重要部件是能区分光谱的分光棱镜系统,它要求与摄象管组合使用。管子的靶面是由光学纤维和光学玻璃材料组成的三合一面板。这种结构能使几个相邻的、尺寸相同的象聚焦在摄象管的同一个靶面上,达到彩色摄象的目的。 A small color television camera optical system introduced in this paper is used on the spacecraft cockpit camera unit. An important part of this optical system is a spectroscopic dichroic prism system, which is required in combination with a camera tube. The tube’s target surface is a three-in-one panel made of optical fiber and optical glass material. This structure enables several adjacent, the same size of the same focus on the camera tube on the same target, to achieve the purpose of color camera.
