Supp. 1 from Covert linear polarization signatures from brilliant white two-dimensional disordered wing structures of the phoenix damselfly NixonM. R. OrrA. G. VukusicP. 2017 (A) Example binary image of the <i>Pseduolestes mirabilis</i> photonic structure. (B) Averaged results from FFT analyses of binary images of the <i>P. mirabilis</i> structure, such as that shown in (A). The lack of any features in the FFT, apart from the high intensity peak at low spatial frequencies, suggests that there is no discernible order in the structure.
