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

Phase-Sensitive Light: Coherence Theory and Applications to Optical Imaging
TL;DR: This thesis sets out to unify— and generalize—classical and quantum imaging within the framework of Gaussian- state light fields, which encompasses thermal light—the source used in conventional imagers— and biphoton-state light as special instances, and is able to provide a complete understanding of the boundary between classical and quantum behavior in optical coherence tomography, ghost imaging and two-photon imaging.

Comparative resolution and tracking performance in B-mode and short-lag spatial coherence (SLSC) images
TL;DR: The resolution of simulated and experimental SLSC images is highly sensitive to noise and is similar to B-mode images for a range of noise, clutter, and short-lag values.

Spatial resolution, noise and information in the computational-imaging era
TL;DR: An intrinsic duality of spatial resolution and signal-to-noise exists in almost all types of imaging, with the related uncertainty relationship determining a trade-off between the two quantities.

Linear Combinations of the Complex Degrees of Coherence
Zhangrong Mei,Olga Korotkova +1 more
TL;DR: In this paper, the spatial coherence state of light is modeled via mixed linear combinations of N complex degrees of coherence (CDC) and conditions under which such combinations represent a valid CDC.

Imaging magnetic nanostructures using soft x-ray Fourier transform holography
TL;DR: In this article, an experimental application of soft x-ray Fourier-transform holography (FTH) for imaging magnetic samples with nanometer structure size was discussed. But the authors focused on the impact of the experimental apparatus on the image and the influence of the reference structure, the area detector, and the coherence of the radiation delivered by the xray source.

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.
