Computer Holography : Acceleration Algorithms and Hardware Implementations

This book describes algorithms and hardware implementations of computer holography, especially in terms of fast calculation. It summarizes the basics of holography and computer holography and describes how conventional diffraction calculations play a central role. Numerical implementations by actual codes will also be discussed. This book will explain new fast diffraction calculations, such as scaled scalar diffraction. Computer Holography will also explain acceleration algorithms for computer-generated hologram (CGH) generation and digital holography with 3D objects composed of point clouds, using look-up table- (LUT) based algorithms, and a wave front recording plane. 3D objects composed of polygons using tilted plane diffraction, expressed by multi-view images and RGB-D images, will be explained in this book. Digital holography, including inline, off-axis, Gabor digital holography, and phase shift digital holography, will also be explored. This book introduces applications of computer holography, including phase retrieval algorithm, holographic memory, holographic projection, and deep learning in computer holography, while explaining hardware implementations for computer holography. Recently, several parallel processors have been released (for example, multi-core CPU, GPU, Xeon Phi, and FPGA). Readers will learn how to apply algorithms to these processors.

Chapters 1-3 summarizes the basic of holography and computer holography. In Chapter 4 conventional diffraction calculations are described that play a central role in computer holography. We pick up angular spectrum method, Fresnel diffraction, and Fraunhofer diffraction as the conventional diffraction calculations. Numerical implementations by quasi codes will be discussed. Chapter 5 explains acceleration algorithms for CGH generation and digital holography. This chapter includes CGH acceleration algorithms for 3D object composed of point cloud, using LUT(Look-up table) based algorithms, wavefront recording plane, and so forth. Another CGH acceleration for 3D object composed of polygons using tilted plane diffraction will be explained. For digital holography, new fast diffraction calculations will be explained, that is, scaled scalar diffraction and non-uniform-sampled diffraction, and so forth . Numerical implementations by quasi codes will be shown. Chapter 6 explains hardware implementations for computer holography. Recently several parallel processors have been released, for example, multi-core CPU, GPU, Xeon Phi and FPGA. In this chapter, how to implement algorithms to these processors will be discussed. For FPGA implementation, the basic of HDL(Hardware Description Language), and how to estimate the required bit-width of digital circuit in fixed-point number format will be explained as well as the example of circuit design for CGH generation"-- Provided by publisher Content: Chapter 1 Basic of holography.
