自六十年代以来,红外科学技术发展十分迅速。伴随着红外物理理论和实验的研究,新的红外材料、红外器件及红外系统不断研制出来。先进的红外仪器不仅在军事和空间应用中占有极其重要的位置,而且越来越广泛地用于国民经济各部门,如高压输电缆接头发热探测、冶金炉壁壁衬检测、地质矿物遥感、森林探火、乳腺癌诊断等等。然 Infrared science and technology have developed rapidly since the 1960s. With the research of infrared physics theory and experiment, new infrared materials, infrared devices and infrared systems have been developed. Advanced infrared instruments not only occupy an extremely important position in military and space applications, but also are increasingly used in various sectors of the national economy, such as heating detection of HV cable joints, detection of wall lining of metallurgical furnaces, geo-mineral remote sensing, forest Fire detection, breast cancer diagnosis and more.
