We demonstrate the calibration and error estimation for three inexpensive pushbroom imaging spectrometers that operate in the visible/near-infrared range. The instruments were all built at the Naval Research Laboratory from commercial, off-the-shelf

Feature-based imaging spectroscopy methods are effective for identifying materials that exhibit specific well-defined spectral absorption features. As long as a pixel contains a sufficient amount of material so that the absorption retains its predomi

We reiterate the fact that the apparent emissivity of a solid surface can depend on not only the composition and particle size distribution comprising the surface but also on view-angle relative to the bulk surface geometry. We report on experiments

The behavior of a planar plasma‐filled diode (PFD) is examined in the limit in which the mass of the plasma ions is allowed to approach infinity. In this limit the plasma ions are immobilized and act as a fixed, spatially uniform background of posi

The University of Maryland Baltimore County (UMBC) airborne Visible-Near Infrared (VNIR) hyperspectral sensor is a grating spectrometer that collects data in the 380 to 985 nm spectral range with spectral resolution as high as 1.15 nm. This imager is

We present results from an improved ORASIS (Optical Real-time Adaptive Spectral Identification System) hyperspectral-data compression-algorithm that is being implemented on the Naval EarthMap Observer (NEMO) satellite. The algorithm is shown to produ

The primary mission of the Naval EarthMap Observer (NEMO) is to demonstrate the importance of hyperspectral imagery in characterizing the littoral battlespace environment and littoral model development. NEMO will demonstrate real time on-board proces

We compare the results produced by the NRL ORASIS algorithm with those produced by ENVI's Pixel Purity Index. Both procedures attempt to find appropriate estimations of the constituent endmembers.

Recent advances in large format detector arrays and holographic diffraction gratings have made possible the development of imaging spectrographs with high sensitivity and resolution, at relatively low component cost. Several airborne instruments have
