Hyperspectral imaging, like other spectral imaging, collects and processes information from across the electromagnetic spectrum. The goal of hyperspectral imaging is to obtain a spectrum for each pixel in an image of a scene, with the purpose of finding objects, identifying materials or detecting activities. Whereas the human eye sees color of visible light in mostly three bands (long wavelengths – perceived as red, medium wavelengths – perceived as green, and short wavelengths – perceived as blue), spectral imaging divides the spectrum into many more bands. This technique of dividing images into bands can be extended beyond the visible. In hyperspectral imaging, the recorded spectra have fine wavelength resolution and cover a wide range of wavelengths. Hyperspectral imaging measures continuous spectral bands. BaySpec builds hyperspectral sensors for applications in agriculture, geosciences, physics and surveillance.
