Most gases and vapours with a bipolar molecular structure absorb infrared energy. If such a gas is interposed between an object emitting infrared radiation and a thermocamera the gas will absorb some of the infrared radiation and thus cast a shadow on the thermocamera picture. In this assay it is possible to visualise the gas. This method had been used to study pollution with anaesthetic gases and vapours in operating theatres. The vapours of other chemicals used in hospitals and other places of work also have been studied. The method permits the study of dispersion and flow patterns of polluting gases and vapours during work.
大多数具有双极分子结构的气体和蒸汽会吸收红外能量。如果将这种气体置于发射红外辐射的物体与热成像仪之间，该气体将吸收一些红外辐射，从而在热成像仪图像上形成阴影。在这个实验中，可以使气体可视化。这种方法已被用于研究手术室中麻醉气体和蒸汽的污染情况。医院和其他工作场所使用的其他化学品的蒸汽也已得到研究。该方法允许研究工作期间污染气体和蒸汽的扩散和流动模式。
