Polarization Sensitivity in Amphibians

2004
Adult amphibians perform periodic migrations and homing between the sites of reproduction, nutrition, shelter and hibernation. The presence and the extent of site fidelity vary considerably among different amphibian species, and the homeward orientation seems to be restricted almost entirely to the area of previous migratory experience (Sinsch 1992 ...

Linear polarization sensitivity

OSA Annual Meeting, 1993
Remote sensing instruments often contain optical components, such as fold mirrors, diffraction gratings, and detectors, whose efficiency depends on the incident polarization state.

Polarization sensitive diffuser

SPIE Proceedings, 2008
With help of liquid crystal polymers (LCP) a polarization sensitive diffuser has been realized. By using convex microstructures made of LCP and an index matching layer, two distinct functions depending on the orientation of the device and the polarization state of the input light are realized.

Spontaneous Polarization as Polar-Sensitive Structure Manifestation

2021 IEEE International Symposium on Applications of Ferroelectrics (ISAF), 2021
The presence of spontaneous polarization in the pyroelectrics is called into question, since always existing free electric charges make it impossible for any equilibrium and unchanging polarized state. To explain the pyroelectricity and piezoelectricity in polar crystals, it is assumed that they contain the hybridized ionic-covalent polar-sensitive ...

Polarization sensitive detectors

Nuclear Instruments and Methods, 1979
Abstract A review of polarization sensitive detector developments since about 1970 is given. It is primarily directed to applications in low energy nuclear physics and treats particles, excluding electrons, and gamma rays. The field of elementary particle research is excluded. A summary of the theory is included.

The polarization of sensitized fluorescence

Proceedings of the Physical Society, 1967
By means of the selection rule ΣmJ = constant along the axis of a collision between two atoms, it is shown that sensitized fluorescence should in some cases be partially polarized. The degree of polarization of the fluorescence of cadmium vapour sensitized by the presence of mercury vapour is calculated for certain states of polarization of the ...

The sensitivity of income polarization

The Journal of Economic Inequality, 2008
Indkomstpolarisering adskiller sig fra både indkomstfattigdom og indkomstulighed. Det er et lativt nyt operationaliseret begreb. På danske data undersøges poliseringsmålets følsomhed mht forskellige forhold, herunder 1) indkomstbegreb, 2) antal år, der lægges til grund for gennemsnitsindkomst, 3) graden af aversion over for polarisering.

Polarization Sensitivity in Crustaceans

2004
To our knowledge, the first animals in which polarization sensitivity has been demonstrated were certain entomostracan crustaceans (Verkhovskaya 1940) and the horseshoe crab Limulus ( Waterman 1950). However, so far the behavioural or ecological significance of this ability in these arthropods is unknown.

Polarization-Sensitive Techniques

2015
In this chapter, polarization-sensitive techniques for imaging and functional diagnosis of biological tissue are considered. Methods based on the polarization discrimination of a probe-polarized light that is scattered by, or transmitted through, a tissue or a cell structure are described.

Polarization Sensitivity in Reptiles

2004
Although there is much information on the homing capacity of reptiles, the role of celestial cues in time-compensated orientation has been studied only in certain freshwater turtles, land tortoises, alligators, snakes and lizards (Chelazzi 1992). The freshwater turtles Terrapene carolina, Chrysemys picta and Trionyx spinifer use celestial cues to ...
