FLAASH®-IR

EMISSIVITY FROM THERMAL INFRARED HYPERSPECTRAL IMAGERY


Thermal, longwave infrared (LWIR) spectral imagery can be used to fullest advantage only when the effects of the atmosphere have been removed and the data are output in units of emissivity or reflectance of materials in the scene. SSI’s FLAASH®-IR software performs accurate atmospheric correction and temperature-emissivity separation of material properties in the LWIR hyperspectral imagery (HSI) of the ground or outdoor objects.

FEATURES

  • Removes atmospheric features from spectral data in the LWIR fingerprint region
  • Outputs temperature maps and spectral emissivity or reflectance data cubes
  • Accurately processes reflective as well as non-reflective materials for both day- and nighttime data collection
  • No supporting measurements or presence of blackbody materials required
  • Supports any HSI system operating in the LWIR, including SEBASS, TASI, HyperCam, OWL, and HyTES
  • Validated, MODTRAN®-based method, used by Government and academic researchers
  • Developed by the same atmospheric correction experts who developed FLAASH® and QUAC® for VIS/SWIR HSI

Applications

  • Aerial surveys of mineral composition
  • Remote chemical detection and identification
  • Thermography (determines surface temperature independent of emissivity)
  • Atmosphere characterization
  • Industrial, environmental, and defense applications
