Fast colorization for single-band thermal video sequences
Neurocomputing, 2016The color night-vision technology is advantageous to scene interpretation by displaying original monochrome night-vision imagery with colors, leading the future trend of night-vision development. Until recently, the methods of color night-vision are mostly based on multi-band sensor fusion that do not apply to thermal systems which are only sensitive ...

A Compact $Q$ -Band Rectangular Waveguide Thermal Isolator
IEEE Transactions on Microwave Theory and Techniques, 2020We present a new waveguide thermal isolator, based on a simple gap in a standard rectangular waveguide, developed for the $Q$ -band cryogenic receiver of the Sardinia Radio Telescope. The proposed component is very compact and consists of a single module, including both the horizontal and vertical polarization channels and the noise injection ...

Comparison of Dust Detection by Using Reflected Solar Bands and Thermal Bands
Advances in Imaging, 2009Dust detection from solar and thermal bands is compared to investigate the performance of each algorithm. Three different algorithms show reasonable consistency to detect dust layer. The consistency increases with aerosol optical depth (AOD).

An in-Scene Atmospheric Compensation Algorithm for Aster Thermal Band
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Generally, atmospheric correction is a key process before the temperature and emissivity separation (TES). In view of the difficulty and accuracy of acquiring synchronous atmospheric profiles, several in-scene atmospheric correction algorithm have been proposed, one of which is the in-scene atmospheric compensation (ISAC) algorithm.

Thermal stability of band offsets of NiO/GaN
Journal of Vacuum Science & Technology A, 2022NiO is a promising alternative to p-GaN as a hole injection layer for normally-off lateral transistors or low on-resistance vertical heterojunction rectifiers. The valence band offsets of sputtered NiO on c-plane, vertical geometry homoepitaxial GaN structures were measured by x-ray photoelectron spectroscopy as a function of annealing temperatures to ...

Thermalization of a manganin band-cable at 1.4K
Cryogenics, 2009Abstract The thermalization of wires for electrical connections was measured at temperatures of ∼1.4 K in a pumped 4 He cryostat, using a simple but efficient device composed of a band-cable of 50 manganin wires clamped into a heat sink. We applied a varied input power from 1 up to 20 μ W to the wires and we observed that the power ...

Estimation of Detector Biases in MODIS Thermal Emissive Bands
IEEE Transactions on Geoscience and Remote Sensing, 2013The combination of multiple detectors and a double-sided mirror in the Moderate Resolution Imaging Spectroradiometer (MODIS) introduces striping in the imagery despite the use of onboard calibration systems. This results in a sharp unidirectional pattern across scan lines and leads to significant radiometric uncertainties in level-1 radiances, which ...

Broad band infrared thermal detector
Sensors and Actuators, 1984Abstract A broad band thermal detector based on pyroelectric materials with temperature-dependent electrical conductivity is described. This detector combines the properties, notably the frequency response, of a thermistor bolometer and a pyroelectric detector. Suitable choice of the detector parameters provides a uniform frequency response above and

Wide-Band Direct Measurement of Thermal Fluctuations in an Interferometer
Physical Review Letters, 2003We directly measured mechanical thermal fluctuations in mirrors over three decades of frequency range using a short-length Fabry-Perot interferometer. This is the first such measurement at wide off-resonant frequency band that is much lower than mechanical resonant frequencies.

Thermal activation of carriers from a metallic impurity band
Physical Review B, 1993Transport and far-infrared transmission measurements are reported on Si-doped GaAs epitaxial films (n≥ the Mott density n 0 ). The spectra display a 1s→2p resonance and a Drude response that persists to low temperatures. An analysis of the temperature dependence of the spectra gives the activation energy for thermal excitation of carriers from the ...
