摘　　要：相比红外光谱定焦成像系统和红外光谱两档成像系统而言,红外光谱连续变焦成像系统具有连续变化的视场,可对目标进行连续成像,是未来红外光谱成像技术的发展方向。为了提高红外光谱连续变焦成像系统的探测性能、实现低成本、良好的消热差性能,近年来国外开发了一些新技术。概述了国外红外材料、红外探测器、冷光阑等方面的新技术,及这些新技术在红外光谱变焦成像系统中的具体应用,列举了使用新型红外材料实现消热差的红外目标探测连续变焦系统,中波红外、长波红外光谱双波段连续变焦系统,高变焦比红外光谱连续变焦系统,应用可变冷光阑技术的红外光谱连续变焦系统设计实例,作为国内红外光谱变焦成像系统发展的借鉴。Compared with the infrared spectrum fixed focal length system and infrared spectrum dual-zoom system,infrared spectrum continuous zoom imaging system which has continuous variational field of view can track targets sequentially,so it is a research direction in infrared spectrum imaging technology.Some new technologies are presented overseas in order to improve the detection performance,reduce cost and have good athermalized performance in infrared spectrum continuous zoom imaging system.Infrared material,infrared detector and variable aperture,those new technologies are su mmarized and the idiographic application of those new technologies in infrared spectrum continuous zoom imaging system are presented in the paper,for example athermalization of an infrared spectrum zoom lens system with new infrared material for target detection,dual band infrared spectrum continuous zoom imaging system with mid-wave infrared and long-wave infrared,infrared spectrum continuous zoom imaging system with high ratio,nfrared spectrum continuous zoom imaging system with dual F/number.It is useful for the development of chinese infrared continuous zoom imaging system.
