Statistical optics
TLDR
Development of this more comprehensive model of the behavior of light draws upon the use of tools traditionally available to the electrical engineer, such as linear system theory and the theory of stochastic processes.Abstract:
Course Description This is an advanced course in which we explore the field of Statistical Optics. Topics covered include such subjects as the statistical properties of natural (thermal) and laser light, spatial and temporal coherence, effects of partial coherence on optical imaging instruments, effects on imaging due to randomly inhomogeneous media, and a statistical treatment of the detection of light. Development of this more comprehensive model of the behavior of light draws upon the use of tools traditionally available to the electrical engineer, such as linear system theory and the theory of stochastic processes.read more

TL;DR: In this paper, the FLASH soft X-ray free-electron laser was used to reconstruct a coherent diffraction pattern from a nano-structured nonperiodic object, before destroying it at 60,000 K.

A Global Assessment of the SRTM Performance
TL;DR: The NASA/NGA Shuttle Radar Topography Mission (SRTM) collected interferometric radar data which has been used by the Jet Propulsion Laboratory to generate a near-global topography data product for latitudes smaller than 60° as mentioned in this paper.

Contribution de la télédétection satellitale radar pour le suivi des paramètres de surface d'une zone sahélienne agro-pastorale
TL;DR: In this paper, les travaux portent sur une region d'etude situee en zone sahelienne agro-pastorale, where le diffusiometre ERS, caracterise par une forte repetitivite temporelle and une faible resolution spatiale, a montre son potentiel sur des zones pastorales saheliennes.

Incorporating tissue absorption and scattering in rapid ultrasound beam modeling
TL;DR: The hybrid angular spectrum (HAS) approach as discussed by the authors alternates propagation steps between the space and the spatial frequency throughout the inhomogeneous regions of the body; the use of spatial Fourier transforms makes this technique considerably faster than other modeling approaches (about 10 sec for a 141 x 141 x 121 model).

Beam combining and SBS suppression in white noise and pseudo-random modulated amplifiers
TL;DR: In this paper, the enhancement factor of a PRBS and a WNS broadened seed was compared as a function of linewidth and fiber length, and two WNS and PRBS modulated fiber lasers were coherently combined to measure the fringe visibility and coherence length.

High-resolution 3-D refractive index imaging and Its biological applications
TL;DR: 3-D optical diffraction tomography (ODT) is presented to retrieve the 3-D refractive index map of a transparent biological sample and applies them to some interesting biological problems: the study of cell growth and monitoring the effect of drugs on multiple myeloma cells.
