Hyperspectral Imaging
Hyperspectral imaging, or imaging spectroscopy, combines the power of digital imaging and spectroscopy.
Hyperspectral imaging, or imaging spectroscopy, combines the power of digital imaging and spectroscopy.
For each pixel in an image, a hyperspectral camera acquires the light intensity (radiance) for a large number (typically a few tens to several hundred) of contiguous spectral bands. Every pixel in the image thus contains a continuous spectrum (in radiance or reflectance) and can be used to characterize the objects in the scene with great precision and detail.
