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

Laser Brillouin à fibre microstructurée en verre de chaleogénure
TL;DR: In this article, the authors propose to use Brillouin fiber-optic fibers for the realisation of a laser-optique system, which can be used for the defense, the metrologie, and the telecommunications.

The AfriSAR Campaign: Tomographic Analysis With Phase-Screen Correction for P -Band Acquisitions
TL;DR: Data acquired by airborne sensors during the AfriSAR campaign in humid tropical forests of Africa is used to examine the potential of P -band tomographic SAR measurements in estimating forest parameters and suggests that phase-screen correction can significantly improve the vertical profile of radar backscattered power.

Performance of Asynchronous Time-Spreading and Spectrally Coded OCDMA Systems
Sang-Gyu Park,Andrew M. Weiner +1 more
TL;DR: The performance of asynchronous coherent time-spreading optical code-division multiple-access (OCDMA) systems is evaluated semi-analytically and the results are compared with those of spectral coding OCDMA systems using ultrashort pulses.

Split-pulse X-ray photon correlation spectroscopy with seeded X-rays from X-ray laser to study atomic-level dynamics
Yuya Shinohara,Taito Osaka,Ichiro Inoue,Takuya Iwashita,Wojciech Dmowski,Chae Woo Ryu,Yadu Krishnan Sarathchandran,Takeshi Egami,Takeshi Egami +8 more
TL;DR: It is shown that the combination of the SDO and self-seeding of X-rays increases the pulse energy and makes it possible to observe the atomic-scale dynamics in a timescale of picoseconds, and the speckle contrast in scattering from water depends on the delay-time as expected.
