The Camera Device Apr 01, 2017

① camera tubes, electron-beam devices are divided into analysis of the image dissector tube, photomultiplier tube, Super is exploring and vidicon tubes, and so on. New types of cameras use small lead oxide camera tube with optical. All kinds of camera tube with a vacuum bulb, containing the target surface and electron guns. Shot on the scenery through the glass window images from the target surface, using photoelectric emission of the target surface effects or photoconductive effect target illuminance distribution of the corresponding electric potential distribution, optical image into the image. Tube deflection yoke, driven by electron beam pixel progressive scan target surface, each pixel of the scan path signal outputs in sequence.
