相移

One-axial loads as well as proportional and nonproportional multiaxial loads such as torsion and bending with and without phase shift (d= 0 deg and d=90 deg) were applied to the welded conxtruction samples.

Nonreciprocal phase shifter is widely used not only in basic optic devices, suchas optic isolator, or circulator, but also in optic channel power equalization, opticwavelength conversion and optic sensor system.

非互易相移器在光隔离器、环行器等基本光器件，和信道功率均衡、光波长转换、光纤传感系统等方面都有着广泛的应用。

This will result in the fluctuation of the sensitivity of the system because of the existing of the dispersion of the reflection-induced retardance.

由于反射膜上产生的反射相移的色散特性，会使光学电流传感器的灵敏度随光源波长的变化而改变。

Meanwhile, comparative analysis indicates that the same weighting function will be produced between the proposed methods for motion error measurement and the ordinary frequency domain three-point method for straightness error measurement, and the homology and unitarily in nature will be confirmed.

权函数的对比分析表明：先行分离出运动误差的单信道或多信道二次相移数据重组法与先行分离出形状误差的普通频域三点法具有相同的权函数，它们在本质上具有同源性和统一性。

It would result in the fluctuation of the sensitivity of the system because of the existing of the dispersions of the reflection-induced retardance,Verdet constant and the linear birefringence inside the sensing head.

而在传感头中主要是由单层保偏反射膜的反射相移、光学玻璃的Verdet常数以及光学玻璃内的线性双折射这三个因素的色散特性，使得光学电流互感器的灵敏度随光源波长的变化而改变。

With the parameters varies within the range of our study, the simulation results compared with their corresponding monochromatic output show that: the wavelength accumulation effect upon the output is small; therefore, it is reasonable and feasible to employing the monochromatic model to deal with the BGOCS systems with broad-band source; the difference between the accumulation output and the monochromatic output decreases with the increase of the current to be measured in the total wavelength accumulation effect; the effect of the Verdet constant is the greatest, that of the Reflection-Induced-Retardance is intermediate, that of the linear birefringence is the smallest.

仿真结果表明，通过和其相应的单色光模型输出的对比，在研究对象相应参数的具体范围内：波长积累效应对系统输出的影响相对于单色模型输出来说很小，小于10~(-4)，因此在实际研究中采用单色模型是合理的和可行的；在总的波长积累效应中，宽带系统输出与单色模型输出的差距随着待测电流的增大而减小，而且影响最大到最小的因子依次是Verdet常量、反射相移和线性双折射。

As the spectral width (Full width half maximum: FWHM) range from 6nm to 60nm, the simulation results show that the effect of the variation of the FWHM upon the output is small. When only the Verdet constant is considered, the output increased slowly with the increase of the FWHM. The simulation results are verified by the experiment.

当光源光谱宽度在6nm到60nm之间变化时，不同谱线宽度光源对系统输出影响的仿真结果表明：光源谱宽变化对系统输出的影响相对于其单色模型来说，相对变化小于10~(-3)，因此光源谱宽变化对系统输出的影响较小；如果完全消除了线性双折射和反射相移，则系统输出随光源谱宽的增加有微弱的增加：由于Verdet常量的影响最大，所以系统输出随光源谱宽的增加有微弱的增加；实验结果验证了该结论。

In last chapter, two kinds of portable DSPI vibrometer are developed. A new simple and reliable structure for speckle averaging is made up and a circuit to change the phase of wide-band signal (200Hz-100KHz) with keeping amplitude constant is skilfully designed.
