Resolution enhancement for interrogating fiber Bragg grating sensor network using dilated U-Net by Li, Baocheng, Tan, Zhi-Wei, Zhang, Hailiang, Shum, Perry Ping, Hu, Dora Juanjuan, Wong, Liang Jie

“…In addition, the multi-peak signals from the FBG sensor network are often overlapped; this increases the complexity of the resolution enhancement task, especially when the signals have a low signal-to-noise ratio (SNR). Here, we show that deep learning with U-Net architecture can enhance the signal resolution for interrogating the FBG sensor network without hardware modifications. …”
