The Micro-Hyperspec™ is a miniature, lightweight hyperspectral imaging system originally developed for use in Unmanned Ariel Vehicles (UAVs) and Unmanned Ground Vehicles (UGVs). Weighing less than half a kilo and only about 110mm square by 50 mm high, it is considerably more portable than more conventional systems.
Hyperspectral imaging uses a combination of a standard camera system and a spectrograph. As the unit moves over the ground a narrow slice of the scene is captured by a single vertical row of the camera’s detector, while the spectrum of each of these pixels is captured by the horizontal rows of the detector. This data forms a “hypercube” which provides a true (or false colour) picture of the scene, together with the spectral signature of each pixel in the scene.
Using a variety of different cameras and spectrographs the Micro-Hyperspec™ system is available for Ultra Violet, visible, near IR, and IR wavelengths.
Hyperspectral imaging is used in a wide variety of applications, from studying land use and crop disease spread, through monitoring chicken and meat carcases for contamination and spoilage, to examining documents and currency to detect forgeries.
