Companies commercialize VTT technology that miniaturises measuring devices
Originally, VTT developed these optical measurement technologies and the associated micromechanical Fabry-Perot interferometer components for the purpose of carbon dioxide measurements. The technology has many other applications, however. VTT joined together with eight companies in the Tekes-financed FABRY project in order to create business from the technology in the form of new products.
In the course of the project, five of the companies started a product development project of their own based on the project results. So far, two of the companies have launched a new product on the market. Rikola Ltd manufactures and sells the world's smallest hyperspectral camera, which can be used, for example, for surveying fertilisation and irrigation needs in agricultural areas from UAVs. The Irish InnoPharma Labs manufactures Eyemap cameras for the pharmaceutical industry, facilitating rapid verification of the drug ingredients and their distribution in a tablet.
VTT is also in the process of establishing a spin-off company based on this technology, with expected launch in May 2014.
Participants in the 2011 FABRY project (Spectroscopic sensor devices based on novel FABRY-Perot interferometers) coordinated by VTT were Continental Automotive SAS from France (fuel measurements for the automotive industry, onboard sensor); SICK AG from Germany (demanding industrial gas measurements); InnoPharma Labs from Ireland (automatic quality management and control for drug manufacturing in the pharmaceutical industry); Ocean Optics from the United States (optical spectroscopy and Raman spectroscopy); Murata Electronics from Finland (sensor manufacturing for the automotive industry); Rikola Ltd Oy from Finland (cameras for hyperspectral imaging ; manufacturing of spectrometer modules); Okmetic Oyj from Finland (development and manufacturing of high-quality silicon wafer for optical sensor applications) and VTT Memsfab Ltd (manufacturing of MEMS components).
The principle of optical measurement, developed at the end of the 19thcentury, is a widely used technique, for example in astronomy. Expensive scientific instruments are used to identify and measure different materials based on their characteristic spectral lines, thus obtaining information about the composition of the target. VTT has combined this technology with microelectromechanical systems (MEMS), creating an affordable, very small and adjustable spectral filter. This makes it possible to miniaturise an entire measuring laboratory to the size of a small sensor.
