Diffuse White Structural Coloration from Multilayer Reflectors in a Squid

The white stripes of the pyjama squid (Sepioloidea lineolata) contain multilayer reflectors with an unordered plate arrangement, enabling reflectance of diffuse white light over a range of viewing angles. Ultrastructural analysis and mathematical modeling are employed to elucidate functional mechani...

Description
Summary:The white stripes of the pyjama squid (Sepioloidea lineolata) contain multilayer reflectors with an unordered plate arrangement, enabling reflectance of diffuse white light over a range of viewing angles. Ultrastructural analysis and mathematical modeling are employed to elucidate functional mechanisms of diffuse reflectance. This optical system may provide a bio‐inspired template for low‐energy, reflectance‐based synthetic displays.
