Polyspectral cameras (multispectral and hyperspectral) for research (R&D&I) and industrial applications, including artificial vision and online polyspectral (multispectral and hyperspectral) imaging.
Added to traditional spectral analysis (spectroscopy, spectrometers, spectrophotometers, spectrographs, ...) that provides data by wavelength, the polyspectral image provides valuable information. This is due to the ability to take images of the response of products and compounds against different spectral bands (wavelengths) which allows their analysis and identification by optical means: non-contact, non-destructive.
In addition, the ability to take measurements in short times (like the Senop HSC-2) makes the implementation of multispectral or hyperspectral cameras a great help and economy in production lines.
About polyspectral cameras nobody agrees on how far it should be called multispectral and from where hyperspectral, but a good approximation would be
- multispectral camera: measures up to a few spectral bands, maximum of 10
- hyperspectral camera: measures from about 10 spectral bands
