Tomographic imaging with harmonic holography in tissues of known refractive index distribution

Demetri Psaltis, Ye Pu

High-resolution imaging in thick biological tissues beyond a few transport mean free path of photons remains a formidable challenge to modern science and technology. Recent advancements in optical tomography have enabled the reconstruction of the three-dim ...

SPIE-INT SOC OPTICAL ENGINEERING2018

, ,

Diffraction properties of thin films of dewetted cyanine dye droplets are investigated and related to the complex refractive index. Strong changes in the index of refraction are often found near the absorption edge of organic dyes. Within a small window of ...

Dimensional Crossover in a Charge Density Wave Material Probed by Angle-Resolved Photoemission Spectroscopy

Matthias Wolf, Helmuth Berger, Christophe Berthod

High-resolution angle-resolved photoemission spectroscopy data reveal evidence of a crossover from one-dimensional (1D) to three-dimensional (3D) behavior in the prototypical charge density wave (CDW) material NbSe3. In the low-temperature 3D regime, gaps ...

Physical bounds on absorption and scattering for cloaked sensors

Romain Christophe Rémy Fleury

We derive and discuss general physical bounds on the electromagnetic scattering and absorption of passive structures. Our theory, based on passivity and power conservation, quantifies the minimum and maximum allowed scattering for an object that absorbs a ...

Retrieval of Particle Scattering Coefficients and Concentrations by Genetic Algorithms in Stratified Lake Water

Alfred Johny Wüest

We retrieved the mass-specific scattering coefficient b(sm)*(lambda) = 0.60.(lambda/650)(-1.82) of the inhomogeneous and optically complex water column of eastern Lake Constance in May 2012. In-situ measured and modelled remote-sensing reflectance R-rs(lam ...

Mdpi Ag2014

The Cold chopper and CAMEA spectrometers are in many ways equivalent. One uses several incoming energies combined with a continuous outgoing energy band while the other use a continuous incoming band and several outgoing energies, and both have big angular ...

Certified reduced basis method for electromagnetic scattering and radar cross section estimation

Jan Sickmann Hesthaven, Yvon Maday

We study nontrivial applications of the reduced basis method (RBM) for electromagnetic applications with an emphasis on scattering and the estimation of radar cross section (RCS). The method and several extensions are explained with two examples with diffe ...

Axial phase measurements of light interacting with microstructures

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We present an experimental method to study field structures of highly confined light after interaction with microstructures. A high-resolution interference microscope (HRIM) allows us to measure the three-dimensional (3D) amplitude and phase distributions ...

Vertical "III-V" V-Shaped Nanomembranes Epitaxially Grown on a Patterned Si[001] Substrate and Their Enhanced Light Scattering

Martin Heiss, Eleonora Russo, Sonia Conesa Boj, Anna Dalmau Mallorquí, Ludovit Pavel Zweifel

We report on a new form of III-IV compound semiconductor nanostructures growing epitaxially as vertical V-shaped nanomembranes on Si(001) and study their light-scattering properties. Precise position control of the InAs nanostructures in regular arrays is ...

, , ,

We present a comparison between sum frequency scattering (SFS) and reflection mode sum frequency generation (R-SFG). We have used scattering theory to describe both scattering experiments as well as reflection mode experiments. The interfacial vibrational ...
