Two-step distortion-free reconstruction scheme for holographic microscopy
Fadwa Joud, Frédéric Verpillat, Max Lesaffre +2
We propose a three-dimensional holographic reconstruction procedure applicable with no a priori knowledge about the recording conditions enabling distortion-free three-dimensional…
Vibration motions studied by Heterodyne Holography
Fadwa Joud, Frédéric Verpillat, Pierre-André TAILLARD +3
Playing with amplitude, phase and frequency of both reference and signal arms, heterodyne holography is well adapted to vibration analysis. Vibration sidebands can be imaged and st…
Three dimensional tracking of gold nanoparticles using digital holographic microscopy
Frédéric Verpillat, Fadwa Joud, Pierre Desbiolles +1
In this paper we present a digital holographic microscope to track gold colloids in three dimensions. We report observations of 100nm gold particles in motion in water. The expecte…
Holographic microscopy for the three-dimensional exploration of light scattering from gold nanomarkers in biological media
Fadwa Joud, Frédéric Verpillat, Pierre Desbiolles +2
The 3D structure of light scattering from dark-field illuminated live 3T3 cells marked with 40 nm gold nanomarkers is explored. For this purpose, we use a high resolution holograph…
Digital Holography at Shot Noise Level
Frédéric Verpillat, Fadwa Joud, Michael Atlan +1
By a proper arrangement of a digital holography setup, that combines off-axis geometry with phase-shifting recording conditions, it is possible to reach the theoretical shot noise…
Exploring shot noise and Laser Doppler imagery with heterodyne holography
Michel Gross, Frédéric Verpillat, Fadwa Joud +1
Heterodyne Holography is a variant of Digital Holography, where the optical frequencies of signal and reference arms can be freely adjusted by acousto-optic modulators. Heterodyne…
Shot Noise in Digital Holography
Fadwa Joud, Frédéric Verpillat, Michael Atlan +2
We discuss on noise in heterodyne holography in an off-axis configuration. We show that, for a weak signal, the noise is dominated by the shot noise on the reference beam. This noi…
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…
Dark-field digital holographic microscopy for 3D-tracking of gold nanoparticles
Frédéric Verpillat, Fadwa Joud, Pierre Desbiolles +1
We present a new technique that combines off-axis Digital Holography and Dark Field Microscopy to track 100nm gold particles diffusing in water. We show that a single hologram is s…
Video-rate laser Doppler vibrometry by heterodyne holography
Benjamin Samson, Frédéric Verpillat, Michel Gross +1
We report a demonstration video-rate heterodyne holography in off-axis configuration. Reconstruction and display of 1 Megapixel holograms is achieved at 24 frames per second, with…
Fringe free holographic measurements of large amplitude vibrations
Fadwa Joud, Frédéric Verpillat, Franck Laloë +3
In the measurement of the amplitude of vibration of objects, holographic imaging techniques usually involve fringe counting; due to the limited resolution of images, measurements o…
Detection of nuclear magnetic resonance with an anisotropic magnetoresistive sensor
F. Verpillat, M. P. Ledbetter, D. Budker +6
We report detection of nuclear magnetic resonance (NMR) using an anisotropic magnetoresistive (AMR) sensor. A ``remote-detection'' arrangement was used, in which protons in flowing…
