Multidimensional polarization sensitivity in damselfishes

Journal of Comparative Physiology A, 2003
Using electroretinogram recording and microspectrophotometry we investigated spectral sensitivity and ultraviolet polarization sensitivity in three species of coral reef fishes commonly known as damselfishes. Here we show that three species of damselfishes (three-spot damselfish, Dascyllus trimaculatus; blacktail damselfish, D.

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.

Polarization sensitive Young interferometer

Optics Communications, 1992
Abstract We describe an interferometer that uses a Wollaston prism and a cosinusoidal grating to produce moire patterns, which are sensitive to the polarization of the optical medium. Experimental results are included.

MODIS Polarization-Sensitivity Analysis

IEEE Transactions on Geoscience and Remote Sensing, 2007
The moderate resolution imaging spectroradiometer (MODIS) is one of the primary instruments in the Earth Observing System (EOS). Currently, MODIS instruments are onboard the NASA EOS Terra and Aqua spacecraft launched in December 1999 and May 2002, respectively. The MODIS reflective solar bands (RSBs) are sensitive to the polarization of incident light,

From Polarization Sensitivity to Polarization Vision

2004
The forerunners of the study of polarization sensitivity in animals are Santschi (1923), Crozier and Mangelsdorf (1924), Verkhovskaya (1940) and Frisch (1949). In one of his behavioural experiments, Santschi depolarized the skylight with a ground glass disk held above an ant running on the ground to its nest.

Polarization sensitive OCT imaging

Proceedings of the Second Joint 24th Annual Conference and the Annual Fall Meeting of the Biomedical Engineering Society] [Engineering in Medicine and Biology, 2002
Imaging the birefringence characteristics of the retinal nerve fiber layer (RNFL) may aid in glaucoma diagnosis. Polarization Sensitive Optical Coherence Tomography (PSOCT) was used to record in vivo high resolution images of the RNFL in two cynomologous monkeys.

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 Fish

2004
Polarization sensitivity (PS) has been studied in several groups of teleost fish with different methods, ranging from orientation experiments to single-unit recordings from the optic tectum. Kawamura et al. (1981), for instance, found that by changing the direction of polarization, the heart-beat rate decreases in several fish species.

Polarization-sensitive OFDI using polarization-multiplexed wavelength-swept laser

Optics Letters, 2014
We demonstrate a novel polarization-sensitive optical frequency domain imaging system employing passive polarization multiplexing. Simple modification of a fiber delay line in the wavelength-swept light source enables illumination with two perpendicular polarizations that are required for determination of the Stokes vector components of the light ...
