在CCD相机的研制工作中,需要将多个CCD安置于CCD相机的焦面位置处,并使各CCD像元之间相对于相机焦面的共焦偏差满足相机设计要求。为了达到这一目的,需要对多个CCD进行焦面测量。文章对各种误差因素在测量过程中的影响进行了分析。
In the development of the CCD camera, a plurality of CCDs need to be arranged on the focal plane of the CCD camera, and the confocal deviation between the CCD pixels relative to the focal plane of the camera satisfies the camera design requirements. In order to achieve this goal, the need for multiple CCD focal plane measurements. The article analyzes the impact of various error factors in the measurement process.
