Every single point in an object has its own specific spectral fingerprint – the spectrum. Spectra can be used to identify and separate different materials and objects.
A hyperspectral camera collects and processes information by measuring the light interaction (reflection, transmission or emission) in order to obtain the Spectrum – the fingerprint - for each pixel in the image of a scene, with the purpose of finding objects, identifying materials, or detecting processes
Hyperspectral cameras can create images that:
A push broom scanner (also known as an along-track scanner) is used for obtaining images using hyperspectral cameras.
The scanners are regularly used in spectral analysis on production lines, food quality assurance, and for passive remote sensors in space.
