热反射是红外热图像解译中常见的问题。特别是，原子光滑的表面，如玻璃、金属或潮湿的表面，以及砖和混凝土，可能很容易产生来自通常不被注意的来源的红外辐射的反射。如果不被注意，这些热反射可能会引起对物体温度的误解。在分析了物体红外辐射和热反射之间的理论差异之后，讨论了利用红外偏振器抑制或至少识别这种反射的可能性。理论预测和实验结果都很有希望。
Thermal reflections are a common source of problems in interpreting infrared (IR) thermal images. In particular, atomically smooth surfaces like glass, metals, or wet surfaces, and also brick and concrete, may easily give rise to reflections of infrared radiation from often uncared sources. If unnoticed, these thermal reflections may give rise to misinterpretations of the object temperature. After analyzing the differences between object IR radiation and thermal reflections theoretically, possibilities to suppress or at least identify such reflections by use of IR polarizers are discussed. Theoretical predictions and experimental results are very promising.
