| Abstract(in English) | A fiber Bragg grating (FBG) sensor using wide and fast mode-locked fiber wavelength-swept laser is demonstrated. The key device is the optical source, wide and fast wavelength-tunable mode-locked fiber laser based on dispersion tuning. This laser has wide tuning range and a fast tunable speed. Hence, it is suited for the dynamic FBG sensor system. Our sensor system enables dynamic measurement of strain in real-time at a high measurement rate. In this system, the signals of the sensor are obtained by analyzing temporal waveforms of reflected light from the FBG without observing the spectrum. A measurement speed as high as 1kHz is achieved when the wavelength-tunable source is swept at 1kHz rate. |
