Photonic structures in bird feathers and their optical properties

为了阐明鸟类羽毛结构色的形成机理，我们对包括岩鸽和孔雀在内的几种鸟类羽毛的显微结构和光学性质进行了研究。特别是，对于岩鸽，几个结构元素已被仔细表征和结构着色的综合机制已被阐明。此外，人们还发现，特殊的视觉效果是通过光谱线形状和视觉的颜色敏感度之间的对应来实现的。

In order to clarify the mechanisms of the structural colors of bird feathers, we have investigated microstructures and optical properties of the feather of several species of birds including the rock dove and peacock. In particular, for rock dove, several structural elements have been carefully characterized and the comprehensive mechanisms of the structural coloration have been elucidated. In addition, it has been found that the peculiar visual effects are realized by the correspondence between the spectral line shape and the color sensitivities of vision.
