真空光敏探测器仍是探测弱光信号和图像的标准器件。在四十余年的发展中,光电倍增管和像增强器已经从实验室研究进入广泛地应用于各种仪器。光电倍增管用在要求高速响应的微弱幅射场合。而像增强器用于要求输出像比输入像更亮的场合或者用于要
Vacuum photodetectors are still standard devices for detecting weak signals and images. In more than four decades of development, photomultiplier tubes and image intensifiers have been widely used in a variety of instruments from laboratory research. Photomultiplier tubes are used in applications that require high-speed response to weak radiation. The image intensifier is used to require the output to be lighter than the input image or to be used
