Band-to-band tunneling and thermal generation gate-induced drain leakage
IEEE Transactions on Electron Devices, 1988MOSFET oxide scaling for DRAM (dynamic random-access memory) applications can be limited by gate-induced diode leakage, which has been shown previously by experiments at cryogenic temperatures to consist of a thermal volume generation and a band-to-band tunneling mechanism. Tunneling is the dominant mechanism at relatively higher voltages and cryogenic

Thermal band selection for the PRISM instrument: 3. Optimal band configurations
Journal of Geophysical Research: Atmospheres, 1998The European Space Agency (ESA) is presently supporting the Processes Research by Imaging Space Mission (PRISM), a project whose aim is the accurate retrieval of land surface temperature (LST) using a new thermal radiometer. Two previous papers have already addressed some aspects of the design and performance requirements for this thermal sensor: the ...

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 ...

Thermal imaging in the extended shortwave infrared band
Applied OpticsThe extended shortwave infrared (eSWIR) band, spanning the wavelengths between 2 and 2.6 µm, lies between the traditional reflective and emissive bands. The eSWIR band receives fewer thermal photons from terrestrial targets than the midwave infrared (MWIR) or longwave infrared (LWIR) bands by several orders of magnitude, but ...

Electronic crosstalk in Terra MODIS thermal emissive bands
SPIE Proceedings, 2015The MODerate-resolution Imaging Spectroradiometer (MODIS) is a legacy Earth remote sensing instrument in the National Aeronautics and Space Administration (NASA) Earth Observing System (EOS). The first MODIS instrument was launched in December 1999 on board the Terra spacecraft.

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.

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 ...

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).

Colorizing single-band thermal night vision images
2010 IEEE International Conference on Image Processing, 2010We consider the problem of assigning single-band thermal night vision image with natural day-time color appearance automatically. We present an approach in which supervised learning is first used to estimate colors of monochromic images. Modeling color distribution of thermal imagery is a challenging problem, since there are insufficient local features

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 ...
