Abstract

Hyperspectral imaging (HSI) spectrometers are remote sensing instruments that acquire images in a large number, typically hundreds, of contiguous spectral channels throughout the visible to long-wave infrared (IR) portions of the spectrum from 0.4 to 14 µm.1 These systems are usually flown on aircraft platforms and use either platform motion or mirror mechanisms to scan a region of the earth's surface. The high-resolution spectral features represented in the data cube allow for discrimination of materials in a scene. Because of the large number of spectral channels that are acquired by these instruments, they are termed hyperspectral, in contrast to multispectral instruments that obtain relatively few spectral bands. Like all remote sensing technologies, HSI must contend with data perturbations caused by atmospheric effects. In addition, data analysis must account for spectral mixing of multiple constituent materials within each pixel's field of view (FOV).
