Optical sensor and module technologies


VTT has a very strong tradition in optical sensor and module technology. There are research groups in Oulu, Espoo and Kuopio with related experience. In addition to optical competencies, the teams have strong domain expertise from various industries. Optical sensors and module technologies are a large and increasing part of our R&D offering. The majority of the devices developed by us will be installed in process monitoring instruments and diagnostic test readers. We have participated in large European and American joint projects in the areas of space technology and remote sensing, for instance. The process measurement technologies focus particularly on the development of spectroscopic measurement principles, modelling, and better calibration techniques and methods. VTT has an extremely strong background in industrial measurements applying optical sensors and modules, such as surface inspection in the pulp and paper industry, quality inspection in the steel industry, pharmaceutical quality control, measurements in bulk manufacturing, and micro- and biotechnology.


Dynamic economic growth and the future viability of companies in global competition will boost the deployment and implementation of optical sensor and module technology in many branches of business. The overall performance level and functionality of today's optical sensor and module technology cannot meet these requirements, and new solutions must thus be developed.
