“…Thus, when the drag force is nonlinear and the temperature of the medium fluctuates, the power spectrum of the velocity autocorrelation function of the colloidal particles will be described neither by the Lorentzian [Eq. (5)] nor by the Gaussian [Eq. (6)] but by the q-Gaussian [Eq.…”

“…Thus, the velocity of the target can be obtained from the observation of the intensity-modulated laser light. We have developed several self-mixing LDV systems with thin-slice solid-state lasers, such as a selfmixing particle analyzer [5,6] and a flowmeter [6,7]. Solid-state lasers with highly doped active ions having an extremely short absorption length for laser-diode pumping are suitable for thin-slice cavity configurations, and these lasers result in an extremely short photon lifetime compared with fluorescence lifetimes.…”

“…The motion of a moving target can be discussed in detail from the intensity of the modulated wave obtained with high accuracy using self-mixing thin-slice solid-state lasers. We previously demonstrated that self-mixing LDV with a thin-slice solid-state laser is applicable to the rapid sizing of nanosize colloidal particles in dilute samples using the power spectrum of the modulated wave [5,6]. When the subsidence of the particles by gravity can be neglected, each particle in a dilute sample undergoes Brownian motion independently.…”

Colloidal particles in a liquid medium are transported with constant velocity, and dynamic light scattering experiments are performed on the samples by self-mixing laser Doppler velocimetry. The power spectrum of the modulated wave induced by the motion of the colloidal particles cannot be described by the well-known formula for flowing Brownian motion systems, i.e., a combination of Doppler shift, diffusion, and translation. Rather, the power spectrum was found to be described by the q-Gaussian distribution function. The molecular mechanism resulting in this anomalous line shape of the power spectrum is attributed to the anomalous molecular dynamics of colloidal particles in transported dilute samples, which satisfy a nonlinear Langevin equation.

“…DHH has also been used for photothermal studies, where a heating laser modulated at a constant frequency offset creates a modulation of the local refractive index of the sample [4]. For the case of Brownian NPs in solution, techniques such as Dynamic Light Scattering and self-mixing laser have studied the dependence of the recorded signal with the frequency offset induced by the moving NPs, being able to calculate the particles' size and concentration [85]. Our aim here is to study whether the introduction of an heterodyning offset frequency could be used to detect only the Doppler-shifted light scattered by moving particles, while still allowing their accurate localization.…”

iii Dans un cadre plus personnel, je remercie mes supercopines du labo: Emilie, Daria, Camille et Anne. Nos activités multiples en dehors du labo ont adouci les coups intrinsèquesà la thèse: des brunchs, des ateliers cuisine, des sessions de PPG et zumba, la piscine, de nombreuses soirées. . . Et bien sûr je remercie aussi mes copains masculins, toujours plus nombreux dans notre domaine, avec lesquels nous avons aussi partagé des très bons moments aussi bienà l'intérieur qu'à l'extérieur du labo: Baptiste, Olivier, Pierre, Nico et Marc. La plupart d'entre eux travaillent et vivent déjà ailleurs; le reste sont, comme moi, en train de dire au revoirà uneépoque importante. Mais mon départ me fait d'autant plus peine car j'ai aussi croisé des gens top sur la fin de cette thèse dont la plupart sont toujoursà Langevin. Heureusement, je suis sûre de revoir François, Fish, Mai, Clément, Nikos, Gautier, Jerôme et Marion sur les pistes de danse! Enfin, je remercie ma famille ainsi que ma famille politique pour leur soutien inconditionnel. Malgré la distance, ils sont restés très près de moi dans les moments les plus importants ces trois dernières années. Un sincère merci aussià mes copains catalans pour leur soutient, compréhension et fidélité de là où ils se trouvent. Cette réussite est aussi grâceà eux et je les porte dans mon coeur partout où je vais. iv AbstractIn this thesis work, we present a novel stochastic microscopy technique based on Digital Holography for the 3D mapping of optical intensity distributions. We show that this far-field, wide-field, 3D microscopy can be turned into both a superresolution and a nearfield imaging technique. To do so, we use metallic nanoparticles undergoing Brownian motion as stochastic local field probes that we localize in three-dimensions in order to overcome the diffraction limit. The random motion of the particles allows for a complete exploration of the sample. Beyond simple localization, the gold markers can actually be envisaged as extremely local electromagnetic field probes, able to scatter light into the far-field. The technique we propose here is therefore a combination of the concepts of superlocalization and NSOM microscopies. The possibilities of the technique are illustrated through the 3D optical mapping of an evanescent and a propagative wave.Fast computation methods allow us to localize hundreds of particles per minute with accuracies as good as 3 × 3 × 10 nm 3 for immobilized particles. In addition to optical intensity mapping, we show a particular application in electrochemistry, by coupling our high resolution images with electrochemical oxidation measurements on silver nanoparticles in solution at the vicinity of an electrode.Our results pave the way for a new subwavelength imaging technique, well adapted to optical characterization in water-based systems (such as in emerging microfluidics studies), which are mostly inaccessible to electron microscopy or local probe microscopies.

application. Thanks to these advantages, this technique has been successfully applied to measuring many physical parameters [2][3][4]. However, little attention is paid to the measurement of particle size or particle size distribution [5]. have demonstrated that the quick evaluation of the submicron particle size in solution by using highly sensitive laser-diode-pumped thin-slice solidstate laser self-mixing interferometry and the self-mixing photon correlation spectroscopy of particle size distributions has been also discussed. Liu et al. [9] have theoretically analyzed the possibility of measuring the nanoparticle size in solution by using erbium-doped fiber ring laser selfmixing interferometry. Zakian et al. [10,11] have applied the laser diode self-mixing interferometry to measuring the nanoparticle size in solution, and the size has been retrieved on basis of the dependence of the full width at half maximum (FWHM) of power spectral density on the nanoparticle size. Wang and Shen [12] have further applied the laser diode self-mixing interferometry to measuring the nanoparticle size distribution in solution, and the size distribution has been retrieved from power spectral density by a modified inversion algorithm.In a flowing Brownian motion system, Sudo et al.[13] have demonstrated that the power spectral density can be reproduced by a single q Gaussian distribution function in which q depends on the diffusion constant of colloidal particles. Thus, by fitting the q parameter of the Gaussian distribution function to the measured power spectrum, the particle size can be easily deduced from the diffusion constant using the Stokes-Einstein relation. Recently, Wang and Shen [14] have developed a quick laser diode self-mixing interferometry for measuring the nanoparticle size distribution. The quick measurement technique is promising to be applied to the online measurement of the nanoparticle size distribution in the flowing Brownian motion system. As far Abstract Laser diode self-mixing interferometry, which is characterized by self-alignment, compactness, low cost and few additional optical elements required, is promising to be applied to the online measurement of the particle size distribution in a flowing Brownian motion system. In this paper, the online measurement is realized by the laser diode self-mixing interferometry with a quick signal processing technique and a quick inversion algorithm. The total power spectrum of the self-mixing signal is achieved, and the impact of particle motions on the total power spectrum is researched. A method is proposed for retrieving the particle size distribution, which is validated by experimental tests.
