| 摘 要： | 数字全息的再现过程是以数字的形式在计算机中完成的,对全息图有关参数的选取影响着数字全息再现像的结果。基于菲涅耳衍射理论和数字全息再现的原理,通过编程进行仿真实验,深入探讨了再现光波长、全息图像素元大小和再现距离等3个主要参数对再现像的影响。仿真实验结果表明,只要这些参数的取值处在合适的范围内,即可得到满足一定要求的清晰再现像。

| Abstract: | Reconstruction processes of digital holography are completed in a computer digitally. And the results of reconstructed images are affected by the selection of related parameters of hol- ograms. Based on Fresnel diffraction theory and the principle of digital holography reconstruction, simulation experiments are realized by programming in this paper. The effects of three main parameters, including the wave length of a reconstruction beam, the pixel size of hol- ograms, the reconstruction distance and so on to reconstructed images of digital holograms are discussed thoroughly. The simulation experimental results show that clear reconstructed images meeting certain requirements could be obtained as long as the values of these parameters are in appropriate ranges. |
