前言光电管的历史悠久,人们早在1890年前后就发现了光电子发射效应,1930年前后就已开始应用。在日本,从1950年起,在线路和路灯的自动开关、有声电影的声音再生等方面开始使用。其后,又研制出各种光电面。现在,由于半导体光探测器处于发展之中,所以,光电管和光电倍增管正在发挥其 Introduction The photoelectric tube has a long history. People discovered the photoelectron emission effect as early as 1890 and started to apply before and after 1930. In Japan, since 1950, it has been used in the automatic switching of lines and streetlights, sound reproduction of sound films and the like. Since then, also developed a variety of photoelectric surface. Now, as semiconductor photodetectors are under development, photomultiplier tubes and photomultiplier tubes are playing their
