Paper Abstract

This paper discusses on off-axis digital holography applied to quantitative imaging of flows. The close link between phase measurement and measurands of interest is discussed. Numerical processing of digital holograms and phase retrieval is summarized. The paper presents different architectures that can be found in literature according to different operating modes: speckle-free mode, speckle mode, reduced-sensitivity, and combined approaches.
