红外热象技术是红外技术中的一个重要方面,它是以目标的红外辐射为依据进行信息处理,输出热图象,并对热象进行分析的技术。从物理学角度看,在绝对零度——-273℃以上的物体,都不断地辐射着红外线,这些红外线的波长、辐出度随物体的温度及表面性质而变化。因此通过对目标辐射的红外线分析研究,可以获得若干有关目标特征的资料及参数。基于这一基本原理,可利用热象技术来进行夜间侦察、空间遥感,还可根据人体热象发现表层癌细胞等等。红外热象仪是这一技术的主要设备。它
Infrared thermal imaging technology is an important aspect of infrared technology. It is based on the infrared radiation of the target for information processing, thermal image output, and thermal image analysis technology. From a physical point of view, infrared radiation is continuously radiated from objects whose absolute zero is above -273°C. The wavelength and the divergence of these infrared rays vary with the object’s temperature and surface properties. Therefore, by analyzing the infrared radiation of the target radiation, several data and parameters related to the target characteristics can be obtained. Based on this basic principle, thermal imaging technology can be used for nighttime reconnaissance, space remote sensing, and surface cancer cells can be found based on human thermal images. Infrared thermal imager is the main equipment of this technology. it
