Morpho butterfly wings as imaging sensor

Detection of infrared radiation using the biological structures gathered increasing attention over the last decade [1, 2], as the need for faster, more sensitive infrared imaging sensors grows ever stronger. Among the proposed techniques for the interrogation of the radiation-induced effects, digital holographic interferometry stands out as the simplest method for obtaining the spatio-temporal information about the response [3]. Using similar methods as described previously [3], with the radiation wavelengths of 405 nm, 450 nm, 660 nm and 980 nm, we prove that the natural structures found on the wing scales of the Morpho Didius butterfly can be used for the detection of radiation throughout the visible and near-infrared part of the optical spectrum
