Comparative study of laboratory and commercial limited-angle holographic tomography setups

摘要

Limited angle holographic tomography (LAHT) is currently the most common tool in biomedical applicationsof 3D quantitative phase imaging. It uses the refractive index (RI) as contrast agent for a single cell or tissueanalysis and provides highly accurate RI values in the full measurement volume. Recently several new systemshave been built in laboratories and new devices have been released into the market. All of them apply algorithmsand processing paths which significantly influence correctness of the results. In our work we perform study ofthe selected LAHT systems and compare their 3D metrological features and other functional parameters.
