一、摄象器件的发展概况电视摄象器件的历史,即是光电变换技术的历史,同时也是电视本身的历史。1873年,英国的Smith和May发现了硒的光电效应,这是电视研究的开端。1931年,美国的Farans-Worth第一个成功地试制了摄象管——析象管。这是一种非存储型(即微分型)摄象管,它的缺点是光的利用率和灵敏度低,1933年美国RCA公司的Zworykin首次研制成光电析象管,这就是现在普遍采用的存储型(即积分型)摄象管。目前黑白广播电视仍广泛使用的超正析象管,它是1946年美国RCA公司的Rose和Weimer等人研制成功的,在适当的照明条 First, the development of imaging devices Overview The history of television camera devices, that is, the history of photoelectric conversion technology, but also the history of the television itself. In 1873, the British Smith and May discovered the photoelectric effect of selenium, which is the beginning of television research. In 1931, Farans-Worth, the United States, first succeeded in making a video tube - the image tube. This is a non-storage type (ie, differential type) video tube, which has the disadvantage of low light utilization and sensitivity, the United States in 1933, Zworykin RCA company developed the first optical tube, which is now commonly used storage Type (ie, integral type) video tube. At present, black-and-white radio and television are still widely used in ultra-true analysis of the CRT, which is the United States in 1946 RCA Rose and Weimer, who successfully developed, in the appropriate lighting strip
