Quantitative phase microscopies: accuracy comparison
Autor: Patrick C. Chaumet, Pierre Bon, Guillaume Maire, Anne Sentenac, Guillaume Baffou
Publikováno v: Light: Science & Applications, Vol 13, Iss 1, Pp 1-29 (2024)
Abstract Quantitative phase microscopies (QPMs) play a pivotal role in bio-imaging, offering unique insights that complement fluorescence imaging. They provide essential data on mass distribution and transport, inaccessible to fluorescence techniques

Scalar approximation of Maxwell equations: derivation and accuracy
Autor: Patrick C. Chaumet, Guillaume Maire, Anne Sentenac
Publikováno v: Journal of the Optical Society of America. A Optics, Image Science, and Vision
Journal of the Optical Society of America. A Optics, Image Science, and Vision, 2022, 39, ⟨10.1364/josaa.462034⟩
International audience; Replacing Maxwell equations by a scalar wave equation is often used in computational imaging to simulate the light-sample interaction. It significantly reduces the computational burden but provides field maps that are insensit

3D label-free imaging with reflection tomographic diffractive microscopy
Autor: Patrick C. Chaumet, Rasedujjaman, Kamal Belkebir, Guillaume Maire, Philippe Robert, Anne Sentenac, Hugues Giovannini
Publikováno v: OSA Imaging and Applied Optics Congress 2021 (3D, COSI, DH, ISA, pcAOP).
Tomographic diffractive microscopy in reflection permits to image the contour of biological cells with high 3D resolution, and has strong potential to monitor important immunological processes, as shown here with preliminary results on phagocytosis.

Reconstruction of surface profile from optical scattered field
Autor: Ahmed Alwakil, Hugues Giovannini, Kamal Belkebir, Gabriel Soriano, Guillaume Maire, A. Talneau
Publikováno v: 2018 International Applied Computational Electromagnetics Society Symposium - China (ACES).
In this work we propose a method for reconstructing the profile of rough surfaces with superresolution from far-field scattering measurements obtained with Tomographic Diffractive Microscopy (TDM). The inversion algorithm used in the reconstruction,
