Signal and Noise scaling factors in digital holography
Max Lesaffre, Nicolas Verrier, Michael Atlan +1
An experimental study on how reconstructed image signal and noise scale with acquisition and reconstruction parameters is proposed. Monte-carlo simulation is performed to emphasize…
3D exploration of light scattering from live cells in the presence of gold nanomarkers using holographic microscopy
Fadwa Joud, N. Warnasooriya, P. Bun +8
In this paper, we explore the 3D structure of light scattering from dark-field illuminated live 3T3 cells in the presence of 40 nm gold nanomarkers. For this purpose, we use a high…
Parallel heterodyne detection of dynamic light scattering spectra from gold nanoparticles diffusing in viscous fluids
Michael Atlan, Pierre Desbiolles, Michel Gross +1
We developed a microscope intended to probe, using a parallel heterodyne receiver, the fluctuation spectrum of light quasi-elastically scattered by gold nanoparticles diffusing in…
Imaging Gold Nanoparticles in Living Cells Environments using Heterodyne Digital Holographic Microscopy
Nilanthi Warnasooriya, Fadwa Joud, Philippe Bun +6
This paper describes an imaging microscopic technique based on heterodyne digital holography where subwavelength-sized gold colloids can be imaged in cell environment. Surface cell…
Imaging of a vibrating object by Sideband Digital Holography
Fadwa Joud, Franck Laloë, Michael Atlan +2
We obtain quantitative measurements of the oscillation amplitude of vibrating objects by using sideband digital holography. The frequency sidebands on the light scattered by the ob…
