These signatures are less pronounced in hyperspectral systems (which image in many more bands than multispectral systems) and when exposed to wind and, more dramatically, to rain. Every material has an infrared signature that aids in the identification of the object. The brightness of the image produced by a thermal imager depends on the objects emissivity and temperature. Because mid-wave infrared (MWIR) and long wave infrared (LWIR) technologies measure radiation inherent to the object and require no external light source, they also are referred to as thermal imaging methods.

This FPA allowed researchers to look at two infrared (IR) planes at the same time. In 2003, researchers at the United States Army Research Laboratory and the Federal Laboratory Collaborative Technology Alliance reported a dual band multispectral imaging focal plane array (FPA). Multispectral imaging measures light emission and is often used in detecting or tracking military targets. Hyperspectral imaging is a special case of spectral imaging where often hundreds of contiguous spectral bands are available. Multispectral imaging measures light in a small number (typically 3 to 15) of spectral bands. Multispectral imaging has also found use in document and painting analysis. Early space-based imaging platforms incorporated multispectral imaging technology to map details of the Earth related to coastal boundaries, vegetation, and landforms. It was originally developed for military target identification and reconnaissance. It can allow extraction of additional information the human eye fails to capture with its visible receptors for red, green and blue. The wavelengths may be separated by filters or detected with the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range, i.e. Multispectral imaging captures image data within specific wavelength ranges across the electromagnetic spectrum.

The Macintosh and Windows versions and documentation on its use are available from the World Wide Web at URL: ∼biehl/MultiSpec/ MultiSpec is copyrighted (1991-2001) by Purdue Research Foundation, West Lafayette, Indiana 47907.Video by SDO simultaneously showing sections of the Sun at various wavelengths Although copyrighted, MultiSpec with its documentation is distributed without charge. Since then most (but not all) of the features in the Macintosh OS version have been ported to the Windows OS version. The GLOBE ( ) program supported the development of a subset of MultiSpec for the Windows OS in 1995. The effort was first begun on the Macintosh OS in 1988. MultiSpec has been implemented for both the Apple Macintosh ® and Microsoft Windows ® operating systems (OS).

It has also found use in displaying and analyzing many other types of non-space related digital imagery, such as medical image data and in K-12 and university level educational activities. The primary purpose for the system was to make new, otherwise complex analysis tools available to the general Earth science community.

It is intended to provide a fast, easy-to-use means for analysis of multispectral image data, such as that from the Landsat, SPOT, MODIS or IKONOS series of Earth observational satellites, hyperspectral data such as that from the Airborne Visible-Infrared Imaging Spectrometer (AVIRIS) and EO-1 Hyperion satellite system or the data that will be produced by the next generation of Earth observational sensors.
