TNO develops dedicated fiber optic sensor systems, which provide sensing solutions where other techniques fail. Intrinsic properties of fiber optic sensing, like e.g. immunity for electromagnetic interference, lightweight, small sized and corrosion resistance are some of the unique features which are fully exploited in many different applications by TNO's fiber optic sensing experts.
As an example this photograph shows two miniaturized fiber optic pressure sensors. The small size is optimized for in-vivo pressure sensing, while TNO's sensor system design, i.e. sensor, readout and data processing algorithms allow a very high pressure sensitivity.
Fiber optic sensing technology provides our customers unique insight in chemical, biological and industrial processes. The sensing principle is based on the interaction of light with its surroundings brought to the measurement location by means of an optical fiber.
There are a number of advantages of using light for sensing combined with a small sized and light weighted optical fiber:
These unique properties fill the gap left by conventional (electrical) sensors and open a whole new area of special applications.
To answer that question let's first take a look at all the different parameters which are accessible using fiber optics: Acceleration, Vibration, Temperature, Strain, Pressure, Shape, Flow velocity, Magnetic field, Liquid level, Density, Viscosity, Humidity, Chemicals. At TNO we develop tailored solutions to your sensing needs. We develop the complete system from sensor to up to the processing algorithms allowing our customers to visualize their process. The sensor system development extends to a prototype level after which we play a consulting role in the first series production of the sensor system. We are in the business of providing unprecedented sensing solutions to our customers, allowing
