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

Optical metrology: methodological analogy and duality revisited
TL;DR: In this paper, the authors present a review that revisits the time-space analogy and signal-frequency duality in optical metrology, as an ode to Jim Wyant and his achievements.

Defect detection during laser welding by laser speckle photometry
TL;DR: In this paper, a laser-multi-pass-narrow-gap-welding (Laser-MPNG) was adapted to be applied in the narrow gaps of up to 200 mm in depth.
Dissertation
A Framework for Inverse Scattering
TL;DR: Inverse scattering as mentioned in this paper is the problem of inverting the light transport process, in order to infer scattering parameters from images of a material, which is a very challenging optimization problem due to the high-dimensional search space and the non-linear dependence of images on scattering parameters.
