By means of the different interference phase formed by light beams with different wavelengths in the same light path difference and the superposing of interference signals of different spectral components, ultimate interference signal is formed.

振动系统产生干涉光路的光程差，形成干涉信号的调制相位差，通过不同光波长在相同光程差条件下形成的不同干涉相位，通过对不同光谱分量的干涉信号叠加，形成最终的干涉信号。

It is found that the changes resulted from the inclination of the moving mirror consists of three parts: the stationary OPD due to the optical beam deflection,the offset OPD due to the different ray in the direction perpendicular to the optical axis,and the offset from the center of the deflected beam to the optical axis.

结果表明，光束偏转带来的误差分为三部分：光束偏转导致整体增加的恒定光程差，垂直光轴方向因不同光线而引入的偏移光程差以及偏转光束中心相对于光轴的偏移量。
