在这篇文章中，我们报告了一个高光谱光学成像应用程序的光子结构，产生高空间分辨率的结构色的反射光谱测量。的光谱反射函数的测量举例说明在蝴蝶翅膀的两个不同种类的鳞翅目：蓝色虹彩反映了若虫Morpho didius和绿色虹彩的凤蝶的凤蝶palinurus。考虑到人类光谱敏感性，计算反射光谱的颜色坐标。对于每个蝴蝶翅膀，观察到的颜色由色度图中的特征颜色图描述，并在颜色空间中的有限体积上扩散。结果表明，反射光谱的变化与覆盖翅膜的鳞片的空间分布中的不同随机排列相关。高光谱光学成像为非侵入性研究和分类结构色中不同形式的不规则性开辟了新途径。
In this article, we report a hyperspectral optical imaging application for measurement of the reflectance spectra of photonic structures that produce structural colors with high spatial resolution. The measurement of the spectral reflectance function is exemplified in the butterfly wings of two different species of Lepidoptera: the blue iridescence reflected by the nymphalid Morpho didius and the green iridescence of the papilionid Papilio palinurus. Color coordinates from reflectance spectra were calculated taking into account human spectral sensitivity. For each butterfly wing, the observed color is described by a characteristic color map in the chromaticity diagram and spreads over a limited volume in the color space. The results suggest that variability in the reflectance spectra is correlated with different random arrangements in the spatial distribution of the scales that cover the wing membranes. Hyperspectral optical imaging opens new ways for the non-invasive study and classification of different forms of irregularity in structural colors.
