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…
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…
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…
Photonic engineering of hybrid metal-organic chromophores
Mickaël P. Busson, Brice Rolly, Brian Stout +3
We experimentally demonstrate control of the absorption and emission properties of individual emitters by photonic antennas in suspension. The method results in a new class of wate…
Acousto-optical coherence tomography with a digital holographic detection scheme
Michel Gross, François Ramaz, Emilie Benoit +2
Acousto-optical coherence tomography (AOCT) consists in using random phase jumps on ultrasound and light to achieve a millimeter resolution when imaging thick scattering media. We…
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…
