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。

在拍摄过程中，采集完参考平面的光场后，只需要再采集一帧条纹图形，通过傅里叶变换、频谱滤波、逆傅里叶变换、相位展开等处理后就能得到物体的三维数据。采用传统的傅里叶变换轮廓术进行三维物体面型测量时，必需保证投影装置出射光瞳和成像装置入射光瞳的连线与参考面平行，并且它们的光轴应在同一平面上，才能得到较为准确的测量结果。

The problem in using titanium dioxide as a photocatalyst is recombination of electron and hole. One strategy for inhibiting theirs recombination is to add other electron accepters to the reaction. It can reduce the electron/hole recombination and then produce more ·OH on the surface of titanium dioxide, from which increased the degradation rate of the pesticide.

We demonstrated ultra-thin tandem WOLEDs by locating yellow and blue emitters at corresponding first antinodes to the metal electrode, instead of 1st and 2nd antinodes in conventional tandem OLEDs. This attempt leads to the substantial reduction of operating voltage improvement in power efficiency, compared to conventional tandem WOLEDs. Besides, it shows stable EL spectra under various bias conditions.
