| 中文摘要 | this paper describes a high-performance multiplexed vibration sensor system using fiber lasers. a serial vibration sensor array consists of four short cavity fiber lasers. the system employs a single, polarization-insensitive, unbalanced michelson interferometer to translate individual laser wavelength shifts induced by vibration signals into interferometer phase shifts. a dense wavelength division demultiplexor (dwdm) with high channel isolation is inserted to demultiplex each laser signal as a wavelength filter. finally, a digital phase demodulator based on the phase generated carrier technique is used to achieve high-resolution interrogation. experimental results show that no observable crosstalk is measured on the output channels, and the minimal detectable acceleration of this system is similar to 200ng/root hz at 250hz, which is fundamentally limited by the frequency noise of the lasers. |
