本文介绍了超级倒象式象增强器及其在夜视系统中的性能,并与其他象增强器的性能作了比较,例如一代三级级联管、二代薄片管、和二代倒象管。性能夜视系统的性能是以观察者在不同景物照度下能够进行分辨来表示的。特别重要的是在很低照度下的性能。系统的性能在很大程度上由象增强器来决定。表示性能特征的三个重要参量是:增益、信噪比(S/N)和分辨率或者调制传递函数(M.T.F)。对于一代管、二代管、和三代管的这些参量值简单评述如下。
In this paper, the super upside-down image intensifier and its performance in the night vision system are introduced and compared with the performance of other image intensifiers such as generation three cascade tube, second generation thin tube, and second generation inverted image tube. Performance Night vision system performance is based on observers in different illumination can be distinguished to represent. Of particular importance is the performance under very low illumination. The performance of the system is largely determined by the image enhancer. The three important parameters that characterize the performance are: gain, signal to noise ratio (S / N) and resolution or modulation transfer function (M.T.F). For the first-generation, second-generation, and third-generation tubes, these parameters are briefly reviewed below.
