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

The photon beam transport and diagnostics system at FERMI@Elettra, the Italian seeded FEL source: commissioning experience and most recent results
Marco Zangrando,A. Abrami,Daniele Cocco,C. Fava,Simone Gerusina,R. Gobessi,Nicola Mahne,Eric Mazzucco,Lorenzo Raimondi,L. Rumiz,Cristian Svetina,Fulvio Parmigiani +11 more
TL;DR: In this paper, the Italian Free Electron Laser (FERMI@Elettra) source is in an advanced commissioning phase, having already delivered radiation down to the endstations, and a dedicated system to collect, diagnose, transport and focus the radiation is used to provide informations about the photon beam intensity, position, spectral content, transverse coherence, and so on.

Speckle in optical lithography and the influence on line width roughness
Oscar Noordman,A. S. Tychkov,Jan Baselmans,James G. Tsacoyeanes,Gary Politi,Michael Patra,Vladan Blahnik,Manfred Maul +7 more
TL;DR: In this article, the spatial distribution of the speckle pattern in optical projection microlithography is investigated and it is shown that the spatial frequencies of the LWR induced by speckles will depend on the illumination condition, which is confirmed experimentally by exposing wafers with different amounts of specule contrast.

Modeling weak fluctuations of undersea telemetry signals
TL;DR: In this article, the authors used the log-intensity fluctuation variances for three major situations: ocean internal waves, ocean turbulence, and continuous strong large-scale turbulence to predict scintillations of intensity up to ranges of tens of kilometers.

Deterministic Terahertz Wave Control in Scattering Media
Vivek Kumar,Vittorio Cecconi,Luke Peters,Jacopo Bertolotti,Alessia Pasquazi,Juan Sebastian Totero Gongora,Marco Peccianti +6 more
TL;DR: In this paper , a deterministic scheme to achieve broadband, spatiotemporal waveform control of terahertz fields mediated by a scattering medium is proposed, and the illumination conditions for an arbitrary targeted output field waveform are deterministically retrieved through numerical inversion.

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.
