Juergen Hildenbrand, Andre Eberhardt, Carolin Peter, Juergen Woellenstein & Jan Korvink
Fabrication process monitoring in industrial applications, safety and environmental monitoring e.g. for the determination of toxic gases are typical fields of applications in modem gas measurement tasks. In the lower price segment solid state devices like metal oxide based gas sensors are typically used. These sensors are very sensitive but they show high cross-sensitivities and a significant signal drift. Optical techniques distinguish by the compensation of these two disadvantages and it is still possible to...
