The phase-shifts caused by reflection and transmission of the beam splitter were investigated by its eigen-martix.The general relationship between these phase-shifts of two splitted beams used for coherent combining was obtained,then the fact that when constructive interference occurs in one side of the beam splitter and the destructive interference has to occur in the other side was explained in the point of phase-shift.

利用分束器的特征矩阵研究了分束时产生的反射与透射相移，得到了两束相干光经过分束器分束后进行相干叠加时相移满足的普适关系，从相移的角度解释了分束器一侧发生相长干涉时另一侧必然发生相消干涉这一现象。

在光四相相移键控系统中，相位噪声主要源于激光器的线宽、激光器的相位偏移、同相支路和正交支路相位不匹配、90°混频器的相位不平衡以及光纤和器件等引起的相位变化。

Methods of fast Fourier transform and phase unwrap were used to demodulate the phase of the interferogram obtained from experiment, distortion of wavefront disturbed by temperature fluctuation which equals to phase shift induced by refractive index change was calculated, and a way of axisymmetric temperature field reconstruction was put into reshowing a layer of the gas temperature distribution.

通过实验得到干涉条纹，用CCD摄入计算机，经Matlab编制傅里叶变换、相位去包裹和其他数值计算程序，解调干涉条纹的相位，计算出温度扰动产生的波面畸变量，它等于折射率变化引起的相位偏移值，用轴对称气体温度场重建方法，再现了气体温度场一个层面上的温度分布。
