Digital Holography (Hardcover)

This book presents a substantial description of the principles and applications of digital holography.

The first part of the book deals with mathematical basics and the linear filtering theory necessary to approach the topic.

The next section describes the fundamentals of the diffraction theory and exhaustively describes the numerical computation of diffracted fields using FFT algorithms. A thorough presentation of the principles of holography and digital holography, including digital color holography, is proposed in the third section.

A special section is devoted to the algorithms and methods for the numerical reconstruction of holograms. A special chapter is devoted to digital holographic interferometry with applications in holographic microscopy, quantitative phase contrast imaging, multidimensional deformation investigations, surface shape measurements, fluid mechanics, refractive index investigations, synthetic aperture imaging and information encrypting. Keys so as to understand differences between digital holography and speckle interferometry and examples of software for hologram reconstructions are also treated briefly.

本書詳細介紹了數位全像術的原理和應用。書中的第一部分介紹了數學基礎和線性濾波理論，這是理解本主題所必需的。接下來的部分詳細描述了繞射理論的基礎，並使用FFT算法全面描述了繞射場的數值計算。第三部分全面介紹了全像術和數位全像術的原理，包括數位彩色全像術。書中還專門介紹了全像術數值重建的算法和方法。其中一個章節專門介紹了數位全像干涉術，並應用於全像顯微術、定量相位對比成像、多維變形研究、表面形狀測量、流體力學、折射率研究、合成孔徑成像和信息加密等領域。此外，本書還簡要介紹了數位全像術和散斑干涉術之間的差異以及全像重建軟體的示例。
