摘要:
为解决分布式拉曼光纤传感系统中光纤损耗及变化带来的测温误差,提出一种带温控光纤环校正双端注入环形结构的解决方案。该方案从光纤两端分时采集得到反斯托克斯拉曼散射信号相乘并进行几何平均,消除了波长相关损耗和局部损耗带来的影响,并利用温控光纤环实时消除光纤损耗变化带来的测温误差。系统还可在传感光纤断裂后瞬时切换成单端注入模式对整条传感光纤进行温度监测。实验结果表明,系统在15°C~210°C的温度范围内得到0.9°C的测量精度。%To eliminate the measurement errors caused by fiber loss and loss variations, a solution employed in Raman distributed fiber sensing system with fiber-ring calibration method and double-ended injection structure is proposed and experimentally demonstrated. Double-ended injection structure adopted in the system eliminates the influence of wavelength-dependent loss and local loss through geometric mean of anti-Stokes Raman scattering signal timesharing obtained from both ends of the sensing fiber. The fiber-ring calibration method is used to correct measurement errors caused by real-time variations of fiber losses. Moreover, with instantaneous switch between double-ended injection structure and single-ended mode, the system can monitor the temperature of the entire fiber even with presence of break point. Experiments show that measurement accuracy of 0.9°C is obtained within temperature range of 15°C~210°C.

摘要:
针对用 Allan 方差方法进行随机误差分析时平均时间只能达到数据长度的一半,以致长相关时间下估计值的置信度较低的问题,本文提出运用高置信度的混合理论方差(TheoH 方差)对光学陀螺进行分析。该方法结合光学陀螺的信号特征,通过改变混合点位置对偏差补偿函数进行改进,提高了估计准确度。运用多种方差估计算法对仿真信号以及光学陀螺实测数据进行分析。实验结果表明,TheoH方差辨识结果和实际的幂律谱噪声特性一致,且具有比Allan方差更高的估计精度。%To solve the problems that the averaging time of Allan variance can only reach half of total data length,and confidence at long averaging time is lower, according to the random errors properties of the inertial sensors at time and frequency domains, a new method for analyzing the random error properties of the inertial sensor based on high confidence and hybrid Allan variance (TheoH variance) is proposed, which can better adapt to the characteristics of optical gyroscope by changing the location of the transition point. The simulated random error of optical gyroscope and measured data of FOG start-up signal are analyzed with the TheoH variance and other variance analysis method. The results show that the estimation values of the TheoH variance are consistent with power-law noise,It can efficiently improve the confidence in the case of great averaging time, and its estimation accuracy is higher than the Allan variance, especially in long termτ- values.

摘要:
提出了一种长周期光纤光栅(Long Period Fiber Grating,LPFG)-布拉格光纤光栅(Fiber Bragg Grating,FBG)多波长解调方法。FBG能够反射LPFG透射光,FBG中心波长的漂移会引起反射光功率的变化,进而改变光电转换电压,从而实现电压对中心波长的解调。由于LPFG的带宽很宽,而FBG的带宽很窄,进而一个LPFG可以实现对多个 FBG 的解调。实验结果表明:FBG 的中心波长和光电转换后的电压有良好的对应关系。该解调方法结构简单,测量精度高,能够实现对温度、应力等参数的多点测量。%A multiple wavelength demodulation method of long period fiber grating and fiber Bragg grating is proposed. Fiber Bragg grating can reflect the long period fiber grating transmission light. The central wavelength shift of fiber Bragg grating will cause the change of reflected light power, and the photoelectric conversion voltage can also change accordingly. So the voltage can demodulate the central wavelength. Because the transmission spectrum of long period fiber grating is very wide, the bandwidth of fiber Bragg grating is so narrow, and a long period fiber grating can demodulate a lot of fiber Bragg gratings. The experimental results show that the voltage of central wavelength and the photoelectric conversion of fiber Bragg grating have a good corresponding relationship. The demodulation method has some advantages including simple structure and high accuracy, so it can be used to measure the parameters of temperature and strain.

摘要:
To analyze the stability of nearly zero flattened dispersion, the dispersion deviations for three kinds of PCFs are calculated when the hole diameters deviate from their designed values. Numerical results show that around the wavelength of 1.55 μm, the dispersion deviations of both the PCF with three-fold symmetry core and the PCF with hexagonal lattice are much less than that of the PCF with different hole diameters in different rings. Therefore, the stabilities of nearly zero flattened dispersion of the first two kinds of PCFs are much better than that of the last one. Considering the confinement loss, the PCF with three-fold symmetry core is preferable to practical use.
