黑白电视摄像机在工业中的应用正在日益扩大,而清晰度直接影响到使用效果.影响清晰度的因素是多方面的,如镜头质量的高低,摄像管工作状态的选择,视频通道特性的调试等,这些性能的提高,可直接改善摄像机的清晰度.一、摄像机的镜头电视摄像机在摄像时,必须使所要摄取的实际景物在摄像管的光电靶面上成像,而这个像必须是清晰的.这就要求光电靶面准确地处于镜头的成像面上.
The application of black and white TV cameras in industry is expanding day by day, and the definition directly affects the effect of use. The factors affecting the definition are many, such as the quality of the camera, the selection of the working state of the video tube, the debugging of video channel characteristics, etc. , These performance improvements can directly improve the clarity of the camera.A camera lens TV camera in the camera, you must make the actual scene to be taken in the camera tube photoelectric target imaging, and this image must be clear. This requires that the optical target be exactly on the imaging surface of the lens.
