Hyperspectral Thermal Emissions Spectrometer (HyTES)

Status

Operated By: 
PI

The Hyperspectral Thermal Emissions Spectrometer (HyTES) instrument has 512 pixels across track with pixel sizes in the range of 5 to 50 m depending on aircraft flying height and 256 spectral channels between 7.5 and 12 µm. The HyTES design is built upon a Quantum Well Infrared Photodetector (QWIP) focal plane array (FPA) , a cryo-cooled Dyson Spectrometer and a high-efficiency, concave blazed grating, produced using E-beam lithography.

HyTES will be useful for a number of applications, including high-resolution surface temperature and emissivity measurements and volcano observations. HyTES measurements will also be used to help determine scientifically optimal band locations for the thermal infrared (TIR) instrument for the Decadal HyspIRI mission.
