A new particle sizing technique based on near field scattering
We present a novel technique for particle sizing based on recent studies about the statistical information contained within the light intensity distribution close to a disordered sample. We show that it is much simpler and more robust than the traditional light scattering methods and any imaging technique. Applications to optical diagnostics, process monitoring and pollution monitoring are expe...
متن کاملPhase imaging and detection in pseudo-heterodyne scattering scanning near-field optical microscopy measurements.
When considering the pseudo-heterodyne mode for detection of the modulus and phase of the near field from scattering scanning near-field optical microscopy (s-SNOM) measurements, processing only the modulus of the signal may produce an undesired constraint in the accessible values of the phase of the near field. A two-dimensional analysis of the signal provided by the data acquisition system ma...
متن کاملConfocal Depolarized Dynamic Light Scattering: a Novel Technique for the Characterization of Nanoparticles in Complex Fluids
5 Structural Biology Brussels, SBB, Vrije Universiteit Brussel, 1050 Brussels, Belgium Corresponding author: Marco A.C. Potenza [email protected] Abstract We present Confocal Depolarized Dynamic Light Scattering as a novel optical method for the characterization of nanoparticles in solution. The method is validated in conditions of biological interest where traditional optical methods fail...
متن کاملSelf-consistent field theories for complex fluids
Recent developments in off-lattice self-consistent field theories for inhomogeneous complex fluids are reviewed. Particular emphasis is given to the treatment of intermolecular interactions and compressibility, to the role of fluctuations, and to the discussion of the coarse-graining length which is inherent to the theory. Valuable insight can be gained from the comparison of self-consistent fi...
متن کاملHeterodyne near-field scanning optical microscopy with spectrally broad sources.
We propose to use low-coherence-length cw optical sources with a broad spectrum in heterodyne near-field scanning microscopy in order to imitate optical pulse propagation and to obtain information about spectrally variant properties of nanophotonic components. The dispersion difference in the interferometer arms for a symmetric acousto-optic modulator arrangement is shown to be negligible over ...
