Multi- and hyper-spectral camera systems
A Dutch company, specialized in advanced measurement equipment, developed a hyper-spectral camera system that can record and analyse more than the eye can see. Images of objects are recorded in multiple wavelengths and can for example prove the presence of specific elements, measuring the quality of samples in an objective way. The system in question combines optics, image acquisition and processing and is small enough to fit into hand-held or airborne systems.
Hyper-spectral camera systems combine imaging and spectroscopy in a single device, which includes large data set processing. It is a non-contact, non-destructive method to quantitatively evaluate the physical and chemical properties of an object, area or phenomenon through the analysis of the rich information of hyper-spectral imaging data. In addition, the measurements are repeatable and data are inter-comparable.
Innovations & Advantages
Satellites use multi-spectral cameras for many years, to study for example vegetation, air pollution or irrigation. Such systems are traditionally quite large and heavy. The Dutch company has, with the help of space technology transfer funds, developed a miniaturised system containing optics, filter and embedded computing, ready to be deployed in field and factory. Remote monitoring of objects or processes with an optical non–destructive inspection system provides real time feedback that can substitute to traditional measurement via sampling and destructive testing. These measurement systems can be integrated in production lines to guarantee the 100% safety and quality of outgoing product, improving food and pharmaceutical standards and mitigating adverse effects on consumer health and company credibility.
