HSI Range LED Lighting for Multispectral and Hyperspectral Imaging
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 -
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
