Coherent imaging from bacteria to multicellular organisms
Structural and functional imaging of cells, tissues and organisms is crucial for understanding biomedical processes. Fluorescence microscopy is an established tool and has contributed to many discoveries in the life sciences. This technique provides molecu ...
EPFL2017Phonon-Mediated Electron Transport through CaO Thin Films
Wolf-Dieter Schneider, Giulia Elisabetta Pacchioni
Scanning tunneling microscopy has developed into a powerful tool for the characterization of conductive surfaces, for which the overlap of tip and sample wave functions determines the image contrast. On insulating layers, as the CaO thin film grown on Mo(0 ...
Amer Physical Soc2015Measurement of absolute cell volume, osmotic membrane water permeability, and refractive index of transmembrane water and solute flux by digital holographic microscopy
Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Pascal Jourdain, Daniel Boss
A dual-wavelength digital holographic microscope to measure absolute volume of living cells is proposed. The optical setup allows us to reconstruct two quantitative phase contrast images at two different wavelengths from a single hologram acquisition. When ...
Spie-Soc Photo-Optical Instrumentation Engineers2013Phase anomalies in Talbot light carpets of selfimages
Hans Peter Herzig, Toralf Scharf, Myun Sik Kim
An interesting feature of light fields is a phase anomaly, which occurs on the optical axis when light is converging as in a focal spot. Since in Talbot images the light is periodically confined in both transverse and axial directions, it remains an open q ...
Optical Society of America2013Resolution and Complex Deconvolution in Holographic Microscopy
Yann Jérôme Michel Pascal Cotte
Interest in high resolution imaging techniques has recently multiplied due to their importance in bio-medical research. Quantitative phase measurements by holographic microscopy is an extraordinary tool to gain new understanding of transparent biological s ...
EPFL2012In vivo assessment of myelination by phase imaging at high magnetic field
Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Rajika Maddage
The present study evaluated the potential of using the phase of T-2* weighted MR images to characterize myelination during brain development and pathology in rodents at 9.4 T. Phase contrast correlated with myelin content assessed by histology and suggests ...
Elsevier2012High-resolution cell outline segmentation and tracking from phase-contrast microscopy images
Jean-Jacques Meister, Charles Brepsant, Mark Etienne Ambühl
Accurate extraction of cell outlines from microscopy images is essential for analysing the dynamics of migrating cells. Phase-contrast microscopy is one of the most common and convenient imaging modalities for observing cell motility because it does not re ...
