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.

Coherence beamforming and its applications to the difficult-to-image patient

TL;DR: Poor quality ultrasound images and inadequate or suboptimal visualization of imaging targets is a common problem in individuals that are overweight or obese and diffuse acoustic reverberation is a significant contributor to the poor image quality.

Broadband resolution analysis for imaging with measurement noise.

TL;DR: The striking effect of aperture-independent superresolution in imaging with broadband signals is demonstrated and is shown to depend also on factors such as the signal-to-noise ratio and the false-alarm rate.

Influence of speckle and Poisson noise on exoplanet detection with a coronagraph

TL;DR: The relative importance of speckle and photon noise is discussed, the limits of coronagraphy for the detection of an exoplanet are presented and simple expressions are obtained for the variances of the noise.

Statistical investigation of the double random phase encoding technique

TL;DR: The amplitude-encoding case of the double random phase encoding technique is examined by defining a cost function as a metric to compare an attempted decryption against the corresponding original input image to quantify the correctness of a decryption key's correctness.

Performance of Nonlinear Receivers in Asynchronous Spectral-Phase-Encoding Optical CDMA Systems

TL;DR: Two most common nonlinear receivers based on second harmonic generation and self-phase modulation effects are analyzed and it is found that, when an m-sequence is used as the spreading code, the encoded signal does not obey Gaussian statistics, and the system performs better than an equivalent system using a random code.
