摘要

所提出的技术包括用于传感器表征的光纤谐振器,实现了改进动态范围的替代技术。这种技术依赖于对由信号饱和引起的附加信号的分析,而信号饱和是由于激光脉冲的增宽而产生的。本文对不同的脉冲宽度进行了广泛的研究,即100 ns、5 μs和20 μs,这是最后一个与所提出的结构产生附加信号有关的脉冲宽度。在存在强度传感器的情况下,波形的行为也被表征。

Analysis of signal saturation in a fiber ring resonator integrating an intensity sensor
The proposed technique consists in an optical fiber resonator interrogated for sensor characterization, implementing an alternative technique for dynamic range improvement. Such technique relies on the analysis of an added-signal caused by signal saturation, which occurs due to the broadening of the laser pulse. A wide study for different pulse widths is presented in this work, namely for 100 ns, 5 μs and 20 μs, being the last one related to the emergence of an added-signal for the proposed configuration. The behavior of the waveform in the presence of an intensity sensor is also characterized.
