Polarized Light in Animal Vision pdf epub mobi txt 电子书 下载 2024
While the human eye can practically cope only with two aspects of light, brightness and colour, many animals use polarization as a further source of visual information. The text starts with an introduction into imaging polarimetry, an efficient technique for measuring light polarization, and moves onto a description of the various polarization patterns occurring in nature, such as celestial polarization.The major part of the book is dedicated to the fascinating question: How do animals use polarization patterns? Following a compendium of the physiology of polarization sensitivity, several case studies are presented, such as honeybees or ants using polarized light as a compass or aquatic animals orientating by the underwater polarization. Further, it is explained how man-made objects affecting the natural optical environment may disorientate animals. For instance, as in the case where oil or glass surfaces can be more attractive for water-seeking polarotactic insects than the water surface.
