A comparison of hologram plane coding and object plane coding on different types of holograms

Digital holography is an imaging technique with great potential, that allows the acquisition and the reproduction of the entire wavefield of light. A big challenge in this field is the development of efficient coding tools, due to the different hologram data characteristics compared to standard multimedia content. This work presents an experimental comparison between two different coding techniques: the well-known hologram plane coding and the less-investigated object plane coding. In order to identify advantages and limitations of each method, but also to determine if the object plane coding could be an effective alternative to the more simple hologram plane coding, different types of holograms are employed, analyzing and discussing the obtained results.
