Phase-resolved heterodyne holographic vibrometry with a strobe local oscillator
Nicolas Verrier, Michel Gross, Michael Atlan
We report a demonstration of phase-resolved vibrometry, in which out-of-plane sinusoidal motion is assessed by heterodyne holography. In heterodyne holography, the beam in the refe…
Phase-space behavior and conditional dynamics of an optomechanical system
S. Groeblacher, S. Gigan, M. Paternostro
We characterize the local properties of an optomechanical system comprising the movable mirror of a resonator and its intracavity field, mutually coupled via radiation-pressure. Ou…
Absolute measurement of small-amplitude vibrations by time-averaged heterodyne holography with a dual local oscillator
Nicolas Verrier, Michael Atlan
We report a demonstration of the measurement of the ratio between an optical modulation side band component and the non-shifted light component by time-averaged heterodyne holograp…
Liberating Higgs couplings in supersymmetry
Christoffer Petersson, Alberto Romagnoni, Riccardo Torre
In the MSSM, the Higgs couplings to down-type quarks and leptons, normalized with respect to their corresponding Standard Model values, coincide at tree-level and this degeneracy i…
Short-time Fourier transform laser Doppler holography
Benjamin Samson, Michael Atlan
We report a demonstration of laser Doppler holography at a sustained acquisition rate of 250 Hz on a 1 Megapixel complementary metal-oxide-semiconductor (CMOS) sensor array and ima…
Thick collagen-based 3D matrices including growth factors to induce neurite outgrowth
M. -N. Labour, Amélie Banc, Audrey Tourrette +5
Designing synthetic microenvironments for cellular investigations is a very active area of research at the crossroads of cell biology and materials science. The present work descri…
