Paper Abstract

In this publication, we give a brief introduction into the field of computational shear interferometry, which allows for determining arbitrary wave fields from a set of shear interferograms. We discuss limitations of the method with respect to the coherence of the underlying wave field and present various numerical methods to recover it from its sheared representations. Finally, we show experimental results on digital holography of objects with rough surfaces using a fiber coupled light-emitting diode and quantitative phase contrast imaging as well as numerical refocusing in differential interference contrast microscopy.
