1. 6. Celestial Orientation in Dim Light

   Författare :Marie Dacke; Funktionell zoologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polarisation pattern; moon; polrised light detection; twilight; dim light; dung beetle; Zoologi; spider; vision; orientation; Zoology;

   Sammanfattning : The polarization pattern of skylight offers many animals a reference for visual compass orientation. In those cases when this optical compass is identified, the receptors involved are often confined to a small part of an eye built predominantly for other visual tasks. LÄS MER

3. 7. Localization using Magnetometers and Light Sensors

   Författare :Niklas Wahlström; Fredrik Gustafsson; Bo Bernhardsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Localization is essential in a variety of applications such as navigation systems, aerospace and surface surveillance, robotics and animal migration studies to mention a few. There are many standard techniques available, where the most common are based on information from satellite or terrestrial radio beacons, radar networks or vision systems. LÄS MER
