故障现象:透视图像模糊。分析检修:图像模糊属于该机电视图像系统的故障,该系统主要由四部分组组成,即Ｘ线影像增强器,光学镜头,Ｘ线电视摄像机及Ｘ线电视监视器。当Ｘ线穿透人体后,形成了一幅相应的电子影像,经过电子透镜的加速的会聚,这幅电子影像就打在增强器的输出屏上,于 Symptom: The perspective image is blurred. Analysis and Maintenance: Image blur belongs to the failure of the aircraft’s TV image system. The system is mainly composed of four parts, namely X-ray image intensifier, optical lens, X-ray television camera and X-ray TV monitor. When the X-ray penetrates the human body, a corresponding electronic image is formed. After the accelerated convergence of the electron lens, the electronic image is played on the output screen of the booster.
