Polarisation effects in natural photonic structures and their applications

S. Berthier,     Université Paris-Diderot, France and Facultés Universitaires Notre Dame de la Paix, Belgium

Abstract:

Electromagnetic waves, unlike those which are generated mechanically, are transverse and introduce polarisation into optic phenomena. Many organisms have photosensitive sensors which enable them to respond to this. Most insects are sensitive to the polarisation of light and are capable of distinguishing two different states of polarisation. This is not the case in primates in general and in hominids in particular. This natural handicap has proved to be a source of bio-inspired innovation, as the use of simple instruments has made it possible to reveal ...
