为了提高光纤Bragg光栅(FBG)波分复用(WDM)传感系统的复用能力,禁忌搜索(TS)算法被引入到快速识别Bragg波长中。在构造光谱过程中考虑串扰效应,达到识别在同一信道下工作的2只高反射率串联光栅信息的目的,使系统的复用能力提高了2倍。TS算法利用光谱的峰值作为搜索初值,有效提升了计算效率,与地毯式搜索(CS)算法相比,运算速度提升了2000余倍。
In order to improve the multiplexing ability of fiber Bragg grating (FBG) wavelength division multiplexing (WDM) sensing system, the tabu search (TS) algorithm is introduced into the fast identification Bragg wavelength. Considering the crosstalk effect in the process of constructing the spectrum and achieving the purpose of identifying two high-reflectivity tandem grating information working under the same channel, the multiplexing capability of the system is improved by two times. The TS algorithm uses the peak value of the spectrum as the search initial value to effectively improve the computational efficiency. Compared with the carpet search (CS) algorithm, the TS algorithm improves the computing speed by more than 2000 times.
