The maturing commercialization of uncooled focal plane arrays and high-density electronics enables lightweight, low cost, small camera packages that can be integrated with headgear. It is only recently that low weight, staring LWIR sensors have become available in uncooled formats at sensitivities that provide enough information for useful manportable wearable applications. By placing the IR ca...

Infrared oil spill detection utilizes either temperature or emissivity contrast of native and oil-covered water surfaces. In particular, the thickness dependent radiance contrast due to thin film interference has been studied. Together with detection boundaries derived from the radiative transfer equation, we can explain historically observed daytime contrast reversal and our observations durin...

We have designed and fabricated two-color infrared light emitting diode (LED) emitting in the wavelength regions of 3–4 lm and 5–10 lm. The interband cascade (IC) LED device was grown on n-type GaSb substrate and has 30 cascaded stages for the long-wave infrared (LWIR) and 15 cascaded stages for the mid-wave infrared (MWIR) emission bands. The two active regions are separated by a 0.5 lm thick ...

This Chapter covers recent advances in Short Wavelength Infrared (SWIR), Medium Wave‐ length Infrared (MWIR) and Long Wavelength Infrared (LWIR) materials and device technol‐ ogies for a variety of defense and commercial applications. Infrared technology is critical for military and security applications, as well as increasingly being used in many commercial products such as medical diagnostics...

The technological advances in efficient, rapid, and non-destructive hyperspectral core logging systems for systematic mineral mapping have led to the discovery exploitation of new deposits Hyperspectral imaging long-wave infrared range has been recently used successfully identify various phosphate-bearing minerals (monazite, xenotime, britholite), with limited work on apatite associated mafic-u...

Abstract We investigated the variation in mineralogical composition of surface soil samples from a wide range atmospheric dust aerosol generating regions. These soils likely have mineral compositions similar to aerosols. measured visible, shortwave infrared (VSWIR) and long wave (LWIR) reflectance spectra, as well LWIR transmission spectra carried out linear spectral mixture modeling on data. T...

1967: 33 Lunar and Planetary Science Conference, March 2002, Houston, Texas. THE COMPTON-BELKOVICH REGION OF THE MOON: J.J. Gillis et al. north of the albedo feature (white arrows in Fig. 2) have very bright sun-facing slopes (i.e., warmer) and dark sun-shaded slopes (i.e. cooler); thus, their reflectance is controlled by topography. The albedo feature, however, is the same temperature in the L...
