Exploring red blood cell membrane dynamics with digital holographic microscopy

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Jonas Kühn, Daniel Boss

Digital Holographic Microscopy (DHM) has been used to investigate the spontaneous cell membrane fluctuations (CMF) of the Red Blood Cell. DHM as an interferometric technique is able to accurately provide the wavefront deformation induced by a transparent s ...

Digital holographic microscopy at fundamental and second harmonic wavelengths

Christian Depeursinge, Etienne Shaffer

Optical second harmonic generation, thanks to its coherent nature, is a suitable signal for interferometric measurements, such as digital holography: a well-established imaging technique that allows recovering of the complex diffraction wavefields from whi ...

Exploring Cell Dynamics with Digital Holographic Microscopy

Pierre Magistretti, Christian Depeursinge, Benjamin Rappaz, Pierre Marquet, Pascal Jourdain, Daniel Boss

Quantitative phase signal (QPS) provided by digital holographic microscopy has permitted to investigate Cellular Membrane nano-Fluctuations (CMnF), of red blood cells as well as to perform an optical measurement of cell electrical activity. ...

We address the problem of zero-order-free image reconstruction in digital holographic microscopy. We show how the goal can be achieved by confining the object-wave modulation to one quadrant of the frequency domain, and by maintaining a reference-wave i ...

Cellular dynamics explored with digital holographic microscopy

Benjamin Rappaz

Obtaining high resolution 3D quantitative images is critical for elucidating the relationship between cell dynamics and physiological or pathological processes. However the feasibility of such cellular dynamic studies is limited by the resolution of the 3D ...
