本文的目的是提请人们注意,象增强管的基本用途可通过近红外光谱探测率的极大提高,将观察能力扩大到较低光级。过去的三十多年中,成象装置取得了重大进展。在军事应用方面,它们有助于车辆、直升飞机的驾驶、武器瞄准和地形侦察。 1.象增强管象增强管的工作原理可用图1说明。由 The purpose of this paper is to draw attention to the basic use of enhancement tubes as a means of extending the viewing power to lower light levels by greatly increasing the detection rate of near infrared spectroscopy. Over the past three decades, significant progress has been made in imaging devices. In military applications, they facilitate the driving of vehicles, helicopters, weapon targeting and topographic reconnaissance. 1. Like to enhance the tube Like to enhance the working principle of the tube can be illustrated in Figure 1. by
