Resumen

The development of novel digital holographic techniques made the research on efficient manage of holographic data more relevant than ever. Specifically, holographic data compression is the subject of intense research, with several proposals based on digital, optical, and optodigital techniques. For this reason, we provide an overview of several data compression techniques and their application to holographic data. We include a discussion about the potential compression ratios achievable with each technique and their inherent limitations. Special attention is given to the problem of compressing the phase obtained from holograms of diffuse objects
