现代战争的需要促进了电光技术的发展.电光技术能使装甲车、防空系统、直升机、步兵和遥控飞行器大大增强作战效率,提高夜间和全天候作战能力.电光系统通常采用两种技术——激光和热成像.热成像系统用于测定目标和背景放射的红外能量,其两大基本组件是探测器和光机扫描器.提出了对未来热成像系统的使用要求和发展方向.详细叙述电光技术在防空系统、直升机和步兵中的应用情况及未来的发展趋势. The need for modern warfare has contributed to the development of electro-optic technology that enables armored vehicles, air defense systems, helicopters, infantry and remotely piloted aircraft to greatly enhance operational efficiency and improve night and day combat capabilities. Electro-optical systems typically employ two technologies - laser and heat Imaging. The thermal imaging system is used to determine the infrared energy radiated by the target and the background. The two basic components are the detector and the optical scanner. The requirements and future directions of the future thermal imaging system are put forward. Helicopters and infantry in the application of the situation and future trends.
