Analysis of Holography Techniques for Phase Distortion Removal in Extreme Environments Open
Holography is an effective diagnostic for the three-dimensional imaging of multiphase and particle-laden flows. Traditional digital inline holography (DIH), however, is subject to distortions from phase delays caused by index-of-refraction…
