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

Strain estimation in phase-sensitive optical coherence elastography
Brendan F. Kennedy,Sze Howe Koh,Robert A. McLaughlin,Kelsey M. Kennedy,Peter R. T. Munro,David D. Sampson +5 more
TL;DR: A theoretical framework for strain estimation in optical coherence elastography (OCE) is presented, based on a statistical analysis of displacement measurements obtained from a mechanically loaded sample, and estimates of strain are derived using three methods: finite difference, ordinary least squares and weighted least squares.
