摘要
讨论了实时全息法应用于检测透明物体的情况下获得高衍射效率和高衬比条纹的若干问题。 给出了同时获得高亮度检测场和高衬比条纹的最佳参数。 在最佳光束比等于1和最佳相位调制度为1.42时, 衍射效率和光能利用率均可达到29%。
Abstract
Some problems on obtaining high efficiency of diffraction and high contrast of interference fringes in real-time holographic interferometry are discussed. The optimum beam ratio and the optimum phase modulation for obtaining high brightness of the testing optical field and high contrast of the interference fringes in real-time holographic interferometry are presented. Both of the diffraction efficiency and the light energy efficiency can be reached to 29% in case of that the optimum beam ratio is 1 and the optimum phase modulation is 1.42.
