Color vision results from the interaction of retinal photopigments with reflected or transmitted visible light. The International Commission on Illumination (CIE) developed the CIE color-matching chart, which separates colors on the basis of the interaction of their spectral profiles with three retinal photopigments in the human eye. We report the development of an infrared chromaticity (CIE-IR) chart, which mimics the CIE chart, in order to discriminate between different chemicals on the basis of the interactions of their IR signatures with three different IR optical filters, instead of the retinal photopigments in the human eye. Our results demonstrate that the CIE-IR chart enables separation of different classes of chemicals, as the visible CIE chart does with color, except for those in the IR spectral region. Such results clearly show that the biomimetic sensing method based on human color vision is in fact a true analogue to color vision and that the proposed CIE-IR chart can be used as a classification method unique to this biomimetic sensing modality.
颜色视觉是由视网膜光感受器与反射或透射可见光的相互作用产生的。国际照明委员会（CIE）开发了 CIE 比色图表，该图表根据其光谱特征与人类眼中的三种视网膜光感受器的相互作用来分离颜色。我们报告了一种红外色度（CIE-IR）图表的开发，该图表模拟了 CIE 图表，以便根据不同化学物质的红外特征与三种不同的红外光学滤光片的相互作用来区分它们，而不是人类眼睛中的视网膜光感受器。我们的结果表明，CIE-IR 图表能够分离不同类别的化学物质，就像可见的 CIE 图表根据颜色来分离一样，除了那些在红外光谱区域内的化学物质。这些结果清楚地表明，基于人类颜色视觉的仿生传感方法实际上是对颜色视觉的真实模拟，并且所提出的 CIE-IR 图表可以用作这种仿生传感模式的独特分类方法。
