Optical elastic scattering for early label-free identification of clinical pathogens
Valentin Genuer, Olivier Gal, Jérémy Méteau +5
We report here on the ability of elastic light scattering in discriminating Gram+, Gram-and yeasts at an early stage of growth (6h). Our technique is non-invasive, low cost and doe…
Control of the differential interference contrast in reinjected bimode laser
Eric Lacot, Olivier Jacquin, Olivier Hugon +1
We have demonstrated, both theoretically and experimentally, that it is possible to control (i.e., to enhance or cancel) the contrast of the interference pattern appearing in the i…
Nonlinear modification of the laser noise power spectrum induced by a frequency-shifted optical feedback
Eric Lacot, Bahram Houchmandzadeh, Vadim Girardeau +2
In this article, we study the non-linear coupling between the stationary (i.e. the beating modulation signal) and transient (i.e. the laser quantum noise) dynamics of a laser subje…
Plenoptic microscope based on laser optical feedback imaging (LOFI)
W Glastre, O Hugon, O Jacquin +2
We present an overview of the performances of a plenoptic microscope which combines the high sensitivity of a laser optical feedback imaging setup , the high resolution of optical…
Self-aligned setup for laser optical feedback imaging insensitive to parasitic optical feedback
Olivier Jacquin, Samuel Heidmann, Eric Lacot +1
In this paper we propose a new optical architecture for the laser optical feedback imaging (LOFI) technique which makes it possible to avoid the adverse effect of the optical paras…
Comparative study of autodyne and heterodyne laser interferometry for imaging
Eric Lacot, Olivier Jacquin, Grégoire Roussely +2
For given laser output power, object under investigation and photodiode noise level, we have theoretically compared the signal to noise ratio (SNR) of a heterodyne scanning imager…

Hervé Gilles, Sylvain Girard, Mathieu Laroche +1
We demonstrate an efficient dynamical amplification of phase conjugation in the gain medium of a diode-pumped Nd3+:YVO4 solid state laser via excitation of its relaxation oscillati…
Effect of speckle on APSCI method and Mueller Imaging
Debajyoti Upadhyay, Michael Richert, Eric Lacot +2
The principle of the polarimetric imaging method called APSCI (Adapted Polarization State Contrast Imaging) is to maximize the polarimetric contrast between an object and its backg…
Deep and optically resolved imaging through scattering media by space-reversed propagation
Wilfried Glastre, Olivier Jacquin, Olivier Hugon +2
We propose a novel technique of microscopy to overcome the effects of both scattering and limitation of the accessible depth due to the objective working distance. By combining Las…
