Hyperspectral Imaging at the Speed of Light

Method of obtaining the spectral content of each pixel in a 2D image. This technology divides the image data, pixel by pixel,into very narrow wavelength (color) bands. The resulting 3D data cube (x, y, λ) allows materials to be identified by their pixel spectral content in addition to their spatial characteristics (see Figure 1). This high-resolution spectral data can effectively recognize unresolved features in the image. It can identify chemical compounds, distinguish camouflage paint from tree canopy, tag recently disturbed earth, and provide data beyond the spatial resolution of the imaging system.
