Holography in multi-phase flows: an improvement in spatial dynamic range and a (potentially) new application

Abstract:

Holography encodes 3-dimensional information in a single 2D image, allowing for the interrogation of complex samples with relatively simple experimental setups.  The majority of the experimental complexity lies in the inversion process, which leverages a physical model for light propagation in free space. Digital data storage and representation brings its own complexities and possibilities. I will present a recent improvement in accuracy and experimental sample size for in-line particle holography, as well as progress in the application of two-source reflective holography to liquid-gas interfaces.
