Hyperspectral technologies and hyperspectral imaging
Hyperspectral technology enables us to detect what our eyes can’t see. The technology allows for a detailed observation of the spectral signature in a range of materials. We can differentiate materials from a distance or detect biological conditions in humans. The data acquired unleashes new opportunities for a wide range of industries from consumer applications such as food and health to remote sensing and Earth observation.
Hyperspectral imaging can be used to identify the chemical composition of an object. The technology can be integrated into mobile phones as well as nanosatellites.
VTT’s hyperspectral technologies enable both low-cost solutions that don’t compromise performance as well as extremely high-performance solutions.
VTT has developed a unique, software-defined, tuneable Fabry-Perot filter technology that allows us to select the spectra we want to analyse.
Hyperspectral technology allows us to see the unseen
Hyperspectral technology allows us to see objects or phenomena that have a spectral signature, at every wavelength. Thus, we are able to see beyond the visible. Going beyond the Red-Green-Blue (RGB) colour space and spectral limitations of the human eye unlocks countless opportunities, such as differentiating materials or detecting biological processes and conditions in humans or in the environment. The technology can be used in anything from microscopes to nanosatellites.
Hyperspectral technology for demanding applications
By expanding our vision system with valuable spectral information, we can see the unseen in many different applications.
In the food sector, for instance, hyperspectral technologies can be employed to analyse food or track macronutrients. For the health industry, hyperspectral technologies provide a way to detect skin cancer, for example. The forest industry benefits from the technology when mapping tree species and monitoring their health using remote sensing.
Other sectors that can benefit from hyperspectral technologies include agriculture, cosmetics and space exploration, just to name a few.
VTT’s core competencies in hyperspectral technology
VTT is focused on researching and developing hyperspectral imaging solutions that can be used in e.g. state-of-the-art hyperspectral cameras for demanding applications as well as low cost, mass manufacturable consumer solutions. Our know-how covers the whole research and development chain from 1) technology development and application 2) unique design 3) prototyping to 4) small-scale manufacturing of sensors.
Our programmable cameras are universal and can be used in any application, at any wavelength.
The hyperspectral technologies developed by VTT enable mobile, low cost and high-performance visible and short-wave infrared hyperspectral imaging.

What’s in store for the future?
We believe hyperspectral imaging is to imaging what digital photography was to film photography. It will empower consumers and industries to see the unseen and deepen our understanding of the world around us. Armed with this knowledge, we can make better-informed decisions and see beyond the obvious.
