The objective is to advise companies that are involved in the development of Non-Destructive Spectral instrumentation by means of spectral repeatability studies, the evaluation of their signal/noise quality and their comparison with other commercial and validated devices, available in our lab sensors unit. The service could include the evaluation of sensors through a large referenced agri-food sample bank available.

Non-destructive spectral devices (NIRS, Hyperspectral, Fluorescence, sensor fusion) are very complex systems that require a range of cross-disciplinary expertise covering fields such as optics, engineering and chemistry. Therefore, their development is extremely challenging as this kind of instruments are also sensitive to changing environmental conditions, so they must have a robust and versatile design to provide a stable, clean and useful signal.In this sense, the objective of this service focuses on the evaluation of NIRS sensors under development through spectral repeatability studies with different types of agri-food samples, providing information on the quality of the instrumental signal, which will help to improve the performance of the device and therefore its marketability. In addition, it is offered to evaluate the signal-to-noise ratio of the equipment in the analysis of different agri-food products, in order to make the spectral information as useful as possible. The performance of the instruments will be compared with other commercially available instruments to assess their capability. For this, we have available a very well-equipped sensor unit lab, with spectral sensors of different technical characteristics, from different brands and multitude of accessories, probes and two pilot conveyor belts. The service might also include the use of a large bank of referenced agri-food samples for the evaluation studies of the instrument under development.
