What is hyperspectral imaging?
Hyperspectral imaging is a combination of spectroscopy and imaging where the light spectrum is split into narrow bands. This can be done in the UV, visible, or NIR.
In certain application, this technique has advantages over color machine vision when very small differences in color must be detected, such as in:
- Optical sorting
- Counterfeit detection
- Skin health
At the 2013 Photonics West Exhibition, Imec provided a great explanation of the advantages of
hyperspectral imaging and their unique approach using the CMOSIS CMV4000, 4 Megapixel, 180 fps (more details in part 2).
First we share the explanation of the benefits of hyperspectral imaging. A generic example was provided by Imec where objects (leaves) that appear very similar in color to the human eye are evaluated using standard color imaging and hyperspectral imaging.
Imec has developed a compact approach without bulky, expensive optics to hyperspectral imaging. Click here for more information.
