Hyperspectral imaging is an emerging technology in machine vision that integrates conventional imaging with spectroscopy. A wide range of new applications for image processing in the visible-NIR region of the spectrum are now possible using this technique.
Hyperspectral imaging enables access to precise measurements of both spectral and spatial information of an object. The acquisition of hyperspectral images starts with an efficient lighting solution with enough spectral and spacial uniformity and a flat spectrum that envenly covers the different wavelengths. When coupled with a hyperspectral camera, it produces the unique spectral signature of the object in the form of a datacube (see illustration below). This technology opens new fields of applications for machine vision in a vast variety of domains.
Here is two example of use for hyperspectral imaging (see the illustrations below).
Hyperspectral imaging for quality control on fishes.
Hyperspectral imaging for analysis of leaves
The HSI range has been developed in close collaboration with hyperspectral camera manufacturers and offers spectra that are suitable for multispectral and hyperspectral applications, from 400nm to 1700nm. The new range HSI is supported by an innovative LED engineered by CCS Inc. This single broadband LED provides exceptionally high spatial and spectral uniformity and thanks to the LED technology, the limitations of halogen lighting can be overcome (lifetime, heat dissipation, stability, and environmental issues).
