Development of a Long Period Fiber Grating Interrogation System Using a Multimode Laser Diode

Development of a Long Period Fiber Grating Interrogation System Using a Multimode Laser Diode

Optical fiber gratings have long shown their sensing capabilities. One of the main challenges, however, is the interrogation method applied, since typical systems tend to use broadband light sources with optical spectrum analyzers, laser scanning units or CCD (Charged Coupled Device) spectrometers....
