A mathematical model of multiple layer skin coloration in cephalopods, a class of aquatic animals, is presented. The model incorporates diffuse and specular reflection from both pigment and structural photonic components found in the skin of these animals. Specific physical processes of this coloration are identified and modeled utilizing available biological materials data. Several examples of combination spectra are calculated to illustrate multiple layer and incident light effects as well as the potentially rich repertoire of color schemes available to these animals. A detailed understanding of the physical principles underlying cephalopod coloration is expected to yield insights into their possible functions.
本文提出了一种头足类动物（一类水生动物）多层皮肤着色的数学模型。该模型纳入了这些动物皮肤中色素和结构光子成分的漫反射和镜面反射。利用现有的生物材料数据，确定并模拟了这种着色的具体物理过程。计算了几个组合光谱的例子，以说明多层和入射光的影响，以及这些动物可能拥有的丰富色彩方案。对头足类动物着色背后物理原理的详细理解有望为其可能的功能提供见解。
