Hyperspectral Sensing Labo
Hyperspectral technology can be useful for many different applications in agrifood processing, for determining (raw) product quality, defects, grading or sorting, etc. By linking spectral and spatial information to reference data, chemometric models can be built for estimating product parameters in real-time.
Services
Testing for proof of concept studies with the devices would be a high investment cost for the company regarding the necessary (spectral) equipment and ICT- and test infrastructure, and it requires specific knowledge and specific (chemometric) software to get reliable, repeatable results for practical applications. Suitable sensors can be selected after testing.
Sensors
The different setups include different sensors, like a mobile high-quality spectrometer that covers the range commonly used in agriculture (the 350 nm to 2500 nm range) and has different probes for different applications. Two hyperspectral cameras (VNIR NIR) are available, next to spectral information, they can also detect spatial information. They can be used in a lab setting or above a conveyor belt. Other sensors include FTNIRS devices for lab measurements, where the samples are rotated and have average point spectra for the products.
