Radiative cooling passively removes heat from objects via emission of thermal radiation to cold space. Suitable radiative cooling materials absorb infrared light while they avoid solar heating by either reflecting or transmitting solar radiation, dep

Target and Background Signatures V.
The scattering properties of materials such as coated and painted surfaces are important in the design of low observable materials. These properties are also important to enable accurate modeling of targets in a scene of different background material

Baseline neurocognitive testing has been recommended to provide a more accurate representation of the pre-concussion cognitive status of individual athletes. Socioeconomic status is not typically controlled for when obtaining baseline scores, which m

Target and Background Signatures IV.
As the sensor technology for polarimetric imaging is advancing into more robust commercial systems such sensors could soon be expected for, e.g., military surveillance and reconnaissance applications in addition to more conventional sensor systems. T

Algorithms and Technologies for Multispectral, Hyperspectral, and Ultraspectral Imagery XXIV.
Hyperspectral imaging in the longwave infrared region (LWIR) offers a unique day and night sensor capability currently not available in other spectral ranges. Current proliferation of the technology is however often limited by the size, weight, power

Algorithms and Technologies for Multispectral, Hyperspectral, and Ultraspectral Imagery XXIV.
This paper presents stand-off measurements with an interferometric LWIR hyperspectral camera, which is based on a corner-cube Michelson interferometer and an uncooled micro-bolometer. Spectrally resolved image data may provide a more robust discrimin

Target and Background Signatures III.
Polarimetric imaging sensors in the electro-optical region, already military and commercially available in both the visual and infrared, show enhanced capabilities for advanced target detection and ...

Scene simulations of optical signature properties using signature codes normally requires input of various parameterized measurement data of surfaces and coatings in order to achieve realistic scene object features. Some of the most important paramet

In this work a spectral designed coating from SPECTROGON is evaluated. Spectral design in this case means that the coating has a reflectivity equal to one at 3-5 and 8-12 microns were sensors operate and a much lower reflectivity in the other wave le
