Looking to the blue sky with colored patterns

Revista Brasileira de Ensino de Física
This work presents a simple alternative technique to observe the polarization of the skylight on Earth. Using a birefringent material and a polarizer to look at the polarized light from the blue sky, it is possible to see a colored pattern that is ...

Exploration of Whether Skylight Polarization Patterns Contain Three-dimensional Attitude Information

, 2020
Our previous work has demonstrated that Rayleigh model, which is widely used in polarized skylight navigation to describe skylight polarization patterns, does not contain three-dimensional (3D) attitude information [1]. However, it is still necessary to further explore whether the skylight polarization patterns contain 3D attitude information.

Advancing Sustainable Development Through Integrated Photovoltaic and Battery Energy Storage Systems in Commercial Buildings: A Strategic, Economic, and Environmental Perspective

Sustainable Development, Volume 33, Issue 6, Page 9144-9164, December 2025.
ABSTRACT Sustainability challenges require advanced and integrated approaches. The key role of SDG 7 can be supported by photovoltaic (PV) systems, which reduce grid dependence during sunlight hours, and by battery energy storage (BES) systems, which enable energy to be stored and utilized when solar generation is not available. The aim of this work is

Bionic Compass Method Based on Atmospheric Polarization Optimization in Non-Ideal Clear Condition

Photonics
The bionic polarization compass is a fascinating subject in the navigation domain. Existing polarization navigation models are primarily based on Rayleigh scattering theory, which is applicable to high-altitude, dry, and clear weather conditions. In most

Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

Functional Ecology, Volume 39, Issue 10, Page 2573-2587, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

Anatomical Reconstruction and Functional Imaging Reveal an Ordered Array of Skylight Polarization Detectors in Drosophila [PDF]

, 2016
Many insects exploit skylight polarization as a compass cue for orientation and navigation. In the fruit fly, Drosophila melanogaster, photoreceptors R7 and R8 in the dorsal rim area (DRA) of the compound eye are specialized to detect the electric vector
