摘要
采用数字全息方法对物体经毛玻璃成像复原机理进行研究。首先,在建立毛玻璃数学模型的基础上,提出了消除毛玻璃干扰的理论算法。然后,利用数字全息再现原理建立了数学模型,并搭建了实验光路,将经毛玻璃后的物体信息通过消除毛玻璃干扰算法后进行再现,并将消除毛玻璃干扰前后的全息图进行了对比分析。最后,通过仿真与实验验证了理论算法和实验方法的正确性,对于物体透过复杂介质成像研究有着极其重要的参考价值。
In this paper,the image restoration of objects through ground glass is studied by digital holography.Firstly,a theoretical algorithml for eliminating the interference of ground glass is proposed,based on the mathematical model of ground glass.Then,the mathematical model is established and the experimental light path is built,based on the principle of digital holographic reconstruction.The information of object after passing through the ground glass is reconstructed after eliminating the interference of ground glass,and hologram after eliminating the interference of ground glass is compared with hologram after the ground glass.Finally,through simulation and experiment,the theo-retical algorithm and experimental method are verified to be correct,which has extremely important reference value for the research on imaging of objects through complex media.
