Direct-Write Digital Holography. Development and research of a hologram printer

John Tapsell

摘要:

第一章简要介绍了全息术的发展历史,并对本文进行了概述。第二章将对全息术进行更详细的描述,并讨论数字全息术。第三章探讨了一个一步单色全息打印机的设计,能够产生白光可见的透射全息图创建的帮助下的LCOS显示系统和打印的点阵序列。所采用的透镜系统包括一个微透镜阵列和一个无焦中继望远镜,这两个定量检查,以最大限度地提高最终的全息图像的对比度,衍射效率和景深。散斑减少技术及其适用于脉冲数字全息的简要概述,以及使用微透镜阵列,以减少散斑效应的实验结果。第四章分析了全息像元角强度分布的副作用,并结合实例进行了分析。第5章探讨了提高全息打印机打印速度和分辨率的方法。第六章介绍了一个温度-能量反馈系统的分析和设计,以校正由于温度变化引起的模式拍频引起的脉冲激光不稳定性。第7章总结了这项工作,并讨论了今后可能的发展。

英文摘要:

Chapter 1 gives a brief history of the field of holography along with an overview of this thesis. A more detailed description of holography is provided in Chapter 2 along with a discussion of digital holography. Chapter 3 examines the design of a one-step monochromatic hologram printer capable producing white-light viewable transmission holograms created with the aid of an LCOS display system and printed in a dot-matrix sequence. The lens system employed includes a microlens array and an afocal relay telescope which are both quantitatively examined in order to maximise the contrast, diffraction efficiency and depth of view of the final hologram image. A brief overview of speckle reduction techniques and their applicability to pulsed digital holography is presented along with experimental results of the use of a microlens array to reduce speckle effects. Chapter 4 presents an analysis of the unwanted side effects of the angular intensity distribution of a hologram pixel, using a case study for analysis. Chapter 5 examines methods for increasing both the printing speed and resolution of the hologram printer. Chapter 6 describes the analysis and design of a temperature-energy feedback system to correct for pulsed laser instabilities arising from mode beating due to temperature variations. Chapter 7 provides a conclusion to the work and discusses possible future developments.
