量子图像中莫尔条纹的理论研究

Theoretical investigation of moiré patterns in quantum images

M. P. Almeida, P. H. Souto Ribeiro, J. A. O. Huguenin, A. Z. Khoury

摘要:

当具有不同空间频率的两个周期性结构叠加时,产生莫尔图案。由此产生的结构的透射引起称为莫尔条纹的空间跳动。在经典光学中,人们对莫尔条纹的兴趣来自于这样一个事实,即由频率差给出的空间拍频给出了关于给定空间结构的细节(高空间频率)的信息。我们表明,莫尔条纹也可以出现在空间分布的符合计数率的孪生光子从参数下转换,当空间结构具有不同的频率被放置在每一个的孪生光束的路径。换句话说,我们演示了如何从量子图像中产生莫尔条纹。

英文摘要:

Moiré patterns are produced when two periodic structures with different spatial frequencies are superposed. The transmission of the resulting structure gives rise to spatial beatings which are called moiré fringes. In classical optics, the interest in moiré fringes comes from the fact that the spatial beating given by the frequency difference gives information about details(high spatial frequency) of a given spatial structure. We show that moiré fringes can also arise in the spatial distribution of the coincidence count rate of twin photons from the parametric down-conversion, when spatial structures with different frequencies are placed in the path of each one of the twin beams. In other words,we demonstrate how moiré fringes can arise from quantum images.
