Correction of radial image distortion in Python using open-source tools
Some techniques of handling holographic data are very sensitive to
optical aberrations the microscope may suffer from. Specifically,
precise stitching of images is very sensitive to radial distortion, even
if the distortion is very weak. We will show how to compensate this
aberration in microscope output using image and data processing
libraries that are available as free software.

Title: Holographic microscopy in low coherence

Author(s): Radim Chmelik, Jiri Petracek, Vera Kollarova, Michala Slaba, CEITEC Brno Univ. of Technology (Czech Republic)
Coherence-controlled holographic microscope (CCHM) makes quantitative phase imaging (QPI) possible with coherent, as well as with incoherent illumination. We have described the imaging process for the whole range of illumination coherence and shown that spatially incoherent light induces optical sectioning in the wide sense due to the coherence gating effect. Thus imposed axial limits of numerical refocusing can be overcome using advanced mode of imaging in CCHM. The effect of low spatial coherence on 3D objects QPI and live cells dry mass density measurement is studied. The theoretical calculations and numerical simulations are supported by experimental data.
