On the wing of the moth Trichoplusia orichalcea a prominent, apparently highly reflective, golden spot can be seen. Scales from this area of the wing exhibit a regular microstructure resembling a submicrometer herringbone pattern. We show that a diffraction process from this structure is responsible for the observed optical properties, such as directionality, brightness variations, polarization, and color.
在粉纹夜蛾翅膀上,可以看到一个明显的、看似高度反光的金色斑点。翅膀这个区域的鳞片呈现出一种规则的微观结构,类似于亚微米级的人字形图案。我们发现,这种结构的衍射过程决定了所观察到的光学特性,如方向性、亮度变化、偏振和颜色。
