Analysis of optical pattern formation on glass: exploring light phenomena in the International Physicists Tournament
Maressa P Sampaio, Renan G Alvim, Felipe K Kalil +2
Motivated by a problem from the 2023 International Physicists' Tournament, we investigate the formation of particular patterns when light passes through glass. Experimentally, we u…
Red Blood Cell Sphericity Index Obtained by Defocusing Microscopy and Retinopathy Severity in Sickle Cell Disease
Camilo Brandao-de-Resende, Ubirajara Agero, Oscar N. Mesquita +2
Proliferative sickle cell retinopathy (PSCR) is the most important ocular manifestation of sickle cell disease (SCD), but understanding of its pathophysiology remains incomplete. R…
Shape reconstruction and height fluctuations of red blood cells using defocusing microscopy
L. Siman, P. M. S. Roma, F. T. Amaral +2
In this paper the bright-field defocusing microscopy (DM) technique is presented. DM is able to obtain quantitative information of each plane/surface of pure phase objects, as live…
Total 3D imaging of phase objects using defocusing microscopy: application to red blood cells
P. M. S. Roma, L. Siman, F. T. Amaral +2
We present Defocusing Microscopy (DM), a bright-field optical microscopy technique able to perform total 3D imaging of transparent objects. By total 3D imaging we mean the determin…
