Study and design of a low cost optical pickup based on double FBGs
چکیده انگلیسی

A fiber Bragg grating (FBG) pickup exploiting Intensity Modulation-Direct Detection (IM-DD) interrogation system was put forward in this paper. The feasibility of detecting the vibration of the guitar was revealed by FFT analysis. There was certain correlation between the FBG pickup and the magnetic pickup. A high signal-to-noise ratio (42.85 dB) was obtained. The FBG pickup has a frequency response range (0–3000 Hz) that is comparable to the reference pickup. The results indicated that the proposed pickup is effective to pick up the vibration. A simple structure design and low-cost interrogation system set-ups were proposed.
