With the increasing interest in holography for 3D imaging applications, there is a need to develop and use hologram compression techniques for the efficient storage and transmission of holographic data. This book gives a broad overview of the state-of-the-art techniques for the efficient compression and representation of digital holographic data, addressing both still and moving data sequences. - An Introduction to the principles of digital holography - A critical analysis of the techniques that have been developed - Coverage of the most recent research results - A summary of future research challenges
