Abstract :
An innovative interrogation system prototype for structural sensing based on a high-performance electro-optic edge filter on glass is presented here. It provides a wavelength dependent transmittance with a linear relationship between the Bragg wavelength shift and the output intensity change of the filter. The resulting device is the demonstration of a simple and inexpensive technology to implement low cost FBG sensors monitoring system based on innovative integrated optic functional component on glass.
