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

Unified theory of ghost imaging with Gaussian-state light
TL;DR: The theory of ghost imaging is developed in a Gaussian-state framework that both encompasses prior work on thermal-state and biphoton-state imagers and provides a complete understanding of the boundary between classical and quantum behavior in such systems as mentioned in this paper.

Efficient reduction of speckle noise in Optical Coherence Tomography
Maciej Szkulmowski,Iwona Gorczynska,Daniel Szlag,Marcin Sylwestrzak,Andrzej Kowalczyk,Maciej Wojtkowski +5 more
TL;DR: This work proposes to average multiple A-scans collected in a fully controlled way to reduce the speckle contrast, which is immune to bulk motion of an investigated sample, and does not require any sophisticated data processing to align cross-sectional images.
