Photonic structures in the skin of pelagic fishes and squids evolved specifically for hiding in the complex light field of the open ocean. To understand the principles under which these structures operate, a detailed characterization of their optical properties is required. An optical scatterometer has been developed to measure one important property, the bidirectional reflectance distribution function (BRDF). The instrument was used to collect reflectance functions from the squid Pterygioteuthis microlampas and fish Sternoptyx sp. Although the animals appear very different to a casual observer, the results reveal interesting similarities in their scattering patterns, suggesting a similar optical strategy for hiding in open water.
远洋鱼类和鱿鱼皮肤中的光子结构是专门为在公海复杂的光场中隐藏而进化的。为了理解这些结构的运作原理，需要对其光学特性进行详细表征。已开发出一种光学散射仪来测量一个重要特性，即双向反射分布函数（BRDF）。该仪器用于收集来自鱿鱼小灯乌贼和鱼类星光鱼的反射函数。尽管在不经意的观察者看来这些动物非常不同，但结果揭示了它们散射模式中有趣的相似之处，这表明在开阔水域隐藏的光学策略相似。
