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,

Parallel detection polarization-sensitive spectrally interferometric polarization-sensitive OCT

SPIE Proceedings, 2004
We will present a new version of the polarization sensitive spectrally interfrometric optical coherence tomography which uses one broadband light source and two measurements to determine the Mueller images of a biomedical sample. This system uses phase information of the OCT images.

On the Polarization Sensitivity of Antenna Arrays

2018 52nd Asilomar Conference on Signals, Systems, and Computers, 2018
The manifold of an array with identical antennas is generally assumed to be insensitive to the polarization of the impinging signal. We show that the manifold of such arrays is generally sensitive to signal polarization and that ignoring this may degrade the performance of direction-of-arrival estimation algorithms, especially for closely spaced ...

Polarization sensitive laser calorimetry

Journal of Applied Physics, 1982
Techniques used currently to determine bulk and surface laser absorption coefficients of highly transparent materials have drawbacks both inherent and practical that limit their accuracy. Conventional bar calorimetry attempts a two-coefficient characterization of nine separate physical absorption sites.

Polarization Sensitivity of Antenna Arrays

IEEE Transactions on Signal Processing, 2019
The manifold of an array with identical antennas is generally assumed to be insensitive to the polarization of the impinging signal except for a complex scale factor which only affects the signal amplitude. Signal polarization is therefore considered in the literature in the context of diversely polarized arrays, which are specifically designed to be ...

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 Photoelectric Conversion

Chemical Reviews
The photoelectric conversion process has traditionally been dominated by studies on light intensity, while the role of polarization remains an emerging and underexplored frontier. Despite the growing number of mechanisms and material architectures demonstrating polarization-sensitive photoelectric responses, a systematic framework to unify these ...

Sensitivity of Ants to Polarized Light

Nature, 1950
THE work of von Frisch1 has shown that the honeybee is sensitive to the plane, and possibly to the degree, of polarization of light. Von Frisch himself suggests that some old observations made by Santschi2 on the homing of ants could be interpreted as suggesting a similar sensitivity.

Polarization Sensitivity in Birds

2004
Birds can use several environmental cues — sun, stars, geomagnetic field, wind direction, odours, landmarks, sound sources, patterns of the intensity, colour and polarization of skylight — for orientation and navigation (Schmidt-Koenig 1979). Until now, only the homing pigeon (Columba livia) has been shown convincingly to possess a sun compass.

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.
