Journal ArticleDOI
Digital holographic microscopy: a noninvasive contrast imaging technique allowing quantitative visualization of living cells with subwavelength axial accuracy.
Pierre Marquet,Benjamin Rappaz,Pierre J. Magistretti,Etienne Cuche,Yves Emery,Tristan Colomb,Christian Depeursinge +6 more
TL;DR: A digital holographic microscope, in a transmission mode, especially dedicated to the quantitative visualization of phase objects such as living cells, is developed, based on an original numerical algorithm presented in detail elsewhere.
Journal ArticleDOI
Measurement of the integral refractive index and dynamic cell morphometry of living cells with digital holographic microscopy
Benjamin Rappaz,Pierre Marquet,Etienne Cuche,Yves Emery,Christian Depeursinge,Pierre J. Magistretti +5 more
TL;DR: A digital holographic microscope adapted to the quantitative study of cellular dynamics, in a transmission mode, and allows to determine independently the thickness and the integral refractive index of cells.
Journal ArticleDOI
Living specimen tomography by digital holographic microscopy: morphometry of testate amoeba
Florian Charrière,Nicolas Pavillon,Tristan Colomb,Christian Depeursinge,Thierry J. Heger,Edward A. D. Mitchell,Pierre Marquet,Benjamin Rappaz +7 more
TL;DR: Morphometric measurements are extracted from the tomographic reconstructions, showing that the commonly used method for testate amoeba biovolume evaluation leads to systematic under evaluations by about 50%.
Journal ArticleDOI
Comparative study of human erythrocytes by digital holographic microscopy, confocal microscopy, and impedance volume analyzer
Benjamin Rappaz,Alexander Barbul,Yves Emery,Rafi Korenstein,Christian Depeursinge,Pierre J. Magistretti,Pierre Marquet +6 more
TL;DR: Digital holographic microscopy in combination with a decoupling procedure allows measuring noninvasively volume, refractive index, and hemoglobin content of single‐living RBCs with a high accuracy.
Journal ArticleDOI
Noninvasive characterization of the fission yeast cell cycle by monitoring dry mass with digital holographic microscopy
Benjamin Rappaz,Elena Cano,Tristan Colomb,Jonas Kühn,Christian Depeursinge,Viesturs Simanis,Pierre J. Magistretti,Pierre Marquet +7 more
TL;DR: This study demonstrates the applicability of DHM as a tool for label-free quantitative analysis of the cell cycle and opens the possibility for its use in high-throughput screening.
