Hyperspectral Sensors and Research

HIGP currently operates AHI (Airborne Hyperspectral Imager) which is an imaging spectrometer covering the spectral range 7.5-11.5 microns. AHI was funded by the Defense Advanced Research Projects Agency (DARPA) to investigate the utility of hyperspectral imaging for detection of buried land mines in a project called the Hyperspectral Mine Detection Program (HMD). The project was very successful, and the AHI system is currently used by the US Army for counter-mine and other research. Professor Lucey was principal investigator for this project, which was a collaboration between the University of Hawaii, Technical Research Associates, and Space Computer Corporation. The University's role was to provide the AHI sensor and support scientific analysis of AHI data, and Professor Lucey was the principal designer of the AHI sensor.

The wavelength range used by AHI is complementary to the more familiar visible and near-IR wavelengths exploited by sensors such as JPL's AVIRIS system because many minerals and materials are spectrally neutral at the shorter wavelengths.
