中文摘要: |
随着光学的发展,全息技术已经在非常多领域显现出它的生命活力,它是一种用途十分广泛的技术,已经被广泛应用于全息显示、全息防伪商标、无损检测、医学及生物工程等诸多领域。但经典的全息技术对光源的相干性要求极高,而我们容易获得的多为非相干光源,这就造成了全息技术发展的局限性。本论文研究空间非相干光的全息干涉,着重在实验和理论上研究“不等臂全息干涉”和“不对称全息干涉”两种全息干涉实验方案,旨在将相干光全息术扩展到非相干光领域,提高全息干涉技术的应用范围,对于全息技术的进一步发展具有很重要的意义。本文的主要内容分为两个部分。
本文前两章为综述性讨论,首先介绍了本论文研究工作的背景及意义;然后简单阐明光场的一阶相干性和二阶相干性理论,描述了鬼干涉的相关内容,并将二阶关联干涉和一阶关联干涉进行对比,对提出本文的研究工作做了铺垫;随后介绍了量子全息和经典全息的联系与区别,对全息技术的发展历程进行了总结,特别介绍了非相干光的一阶关联干涉实验。本论文继续将相干光全息术扩展到非相干光领域,研究空间非相干光场的全息干涉。
本文的第三、四章是介绍空间非相干光的全息干涉研究。提出并完成了两种空间非相干光全息干涉的实验方案,分别是不等臂全息干涉实验方案和不对称全息干涉实验方案。从理论上和实验中都分别证实了这两种实验方案的可行性,并将使用空间非相干光源和空间相干光源的理论与实验结果进行对比,理论分析与实验结果吻合度良好。在空间非相干光源照明下我们设计的两个实验方案都可以得到物体的全息图样,极大的提高了全息技术的应用范围。

外文摘要: |
Holographic technology has shown its vitality in many fields with the development of optics. The classic holographic technology requires the light source with extremely high coherence, however most of light sources we can get are the incoherent light sources. Thus the requirement of coherence obstructs the development of holographic technology. To improve the application range of holographic technology, in this thesis we study the holographic technology with incoherent light field, focusing on experimental and theoretical research on two kinds of holographic interference experiments: the unequal arm holographic interference experimental scheme and the asymmetric holographic interference experimental scheme. The main content of this article is divided into two parts.
The first two chapters of this thesis are review discussions. Firstly, the background and significance of the research work of this thesis are introduced, and the development history of holographic technology is introduced. Then the first-order coherence and second-order coherence theory of the light field are briefly clarified, and the related content of ghost interference is described. Then we introduced quantum holography and classical holographic work, especially the first-order correlation interference experiment of incoherent light. The main research work of this thesis is based on the first-order correlation interference experiment of incoherent light.
In the third and forth chapters of this thesis, two experimental schemes are proposed and completed, which are the unequal arm holographic interference experimental scheme and the asymmetric holographic interference experimental scheme, respectively. The feasibility of the two experimental schemes is confirmed theoretically and experimentally. Both experimental schemes can obtain the hologram pattern of the object, which greatly improves the holographic technology.
