关于全息术一个基本理论问题的研究

About a basic theory problem of holography

1 实验结果 文献[1]认为按图1(a)所得的全息图再现光路可以用图1(b),或图1(c)所示的系统,其中像面是照明光源C的共轭面。文献[2]认为按图1(d)记录的是Fourier变换全息图,输出检测面是Fourier变换透镜的焦平面。文献[1]还认为用图1(e)所记录的Fraunhofer全息图,用与参考波相同的照明光再现时,可以得到如图1(f)所示的结果。

Several reconstruction methods of the Franhofer hologram in theory has been analyzed. It shows that the Fraunhofer hologram is not equal to the Fourier hologram, and the difference between the two image planes is given. The theory is in good agrement with the experiment. Some conclusions different from some papers are presented.
