摄像机结构原理(国外英文资料) Abstract: in this paper, combined with the structure and principles of professional camera and emphasizes the necessity of preliminary inspection failure, with the regional analysis of fault phenomena in, step by step introduction to each part of the idea and method of maintenance, pay attention to the routine maintenance. The camera is a high-tech product that integrates optics, electronics and machinery, so it is more complicated to maintain than the maintenance of the VCR. Its principle and video recording and playback are basically the same, just on the structure of the optical lens system, photoelectric conversion and the corresponding video processing circuit (that is, the construction on the nose). Its not easy to talk about repair. If the mechanics of the machine are not very clear, the analysis circuit is very confusing. Maintenance must truly understand basic principle of the camera, when a fault is analyzed from theory, for fault phenomenon could combine principle according to the circuit diagram (or maintenance manuals) measurement analysis, concluded that differentiate fault area in small area. Of course should also have certain experience, just experience or memorizing some maintenance examples, only some general maintenance fault, have special trouble or slightly change circuit was a hindrance. So as a WeiXiuZhe not only have strong theoretical foundation, familiar with camera principle, to master certain maintenance skills, but also must have a correct maintenance train of thought.  An initial check 1  1  1 as far as possible to the user ask for details of the whole process of machine failure occurs, for example, failure time, process and phenomena. For example, without color or color distortion, ask the machine how to use the environment? Such as temperature, humidity, illumination and color temperature. It is also important to understand the extent of the machine, whether it has been broken, whether it has been repaired, where it
