Optical sensors for lightweights
Modern lightweight materials are increasingly being used in aerospace applications and in other branches, such as traffic and construction engineering, mechanical engineering and the energy business. Fiber composite technology in particular is resulting in huge weight savings.
There are increased attempts to implement sensor technology, either for evaluating ongoing mechanical stress/temperatures or for damage detection, to meet increased safety and warranty standards.
As the number of measurement points to be monitored in an airplane is very high, sensor concepts are needed that are capable of dealing appropriately with information transmission and data handling.
Due to its small dimensions, material conformity and immunity against electromagnetic interference, fiber-optic measurement technology is of particular significance in this area.
The complexity of the entire measurement system can be reduced by transmitting the data for all connected measurement points at the same time through one thin waveguide, resulting in increased stability and availability.
