介绍了各种雄性蝴蝶翅膀美丽颜色的产生机理以及翅膀材料与颜色外观的关系。利用扫描电子显微镜分析了覆盖机翼上表面的鳞片的微观结构。根据薄膜层光干涉理论，利用机翼尺度模型，首次确定了结构彩色尺度颜色产生的基本机理。发现了样品的光学性质与三维光谱反射率的关系，并观察了主观评价中感知到的亮度与基于结构彩色翅膀反射光谱的计算值之间的差异。本研究结果表明，上翼表面的微粗糙度可能会影响结构着色翼的感知光泽度。
This paper describes the mechanism generating the beautiful wing colors of various male butterflies and the relationship between the wing material and the color appearance. The microstructure of the scales covering the upper surface of the wings was analyzed with the aid of a scanning electron microscope. The basic mechanism of color generation of structurally colored scales is determined for the first time in accordance with the theory of optical interference in thin film layers using a model of wing scales. Optical properties were found in relation to the three-dimensional spectral reflectance of the samples, and differences were observed between the brightness perceived in subjective evaluations and calculated values based on the reflective spectra of the structurally colored wings. The results of this study suggest that the microroughness of the upper wing surface may influence the perceived gloss of structurally colored wings.
