一前言十年来红外科学和技术的发展,对红外装置的研制和应用引起了极大的兴趣。这种装置的工艺设计己和光学、电子学以及机械技术密切结合起来。应用的成功要取决于许多“系统”元件的互相作用:目标或辐射能源(天然的或人造的),背景或迭台在目标的辐射上的辐射流图样、目标——敏感元件光学路程及它的特性、光学系统和红外探测器以及探测器输出的处理和显示方法。红外系统通常分为主动和被动两类。在被动系统中,纯粹 A foreword The development of infrared science and technology over the past decade has drawn great interest in the development and application of infrared devices. The process design of such devices has been closely integrated with optics, electronics and mechanical technology. The success of the application depends on the interaction of many “system” elements: the radiation pattern of the target or radiant energy (natural or artificial), the background or the radiation on the target, the target-sensor optical path and its The characteristics of the optical system and infrared detectors and detector output processing and display methods. Infrared systems are usually divided into active and passive two categories. In passive systems, purely
