由于任何物体都会产生红外辐射,温度不同所产生的辐射波长、能量大小就有差异,热成象正是利用这一点,通过景物中各部分温度的差异,把一幅人眼看不见的红外辐射图象转换成一幅可见图象。它无需人工光源照明,而 Because any object will produce infrared radiation, the radiation temperature generated by different wavelengths, there are differences in the size of energy, thermal imaging is the use of this point, through the differences in the temperature of various parts of the scene, the human invisible infrared radiation Converted into a visible image. It does not require artificial lighting, however
