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

Photoacoustic Spatial Coherence Theory and Applications to Coherence-Based Image Contrast and Resolution
TL;DR: The presented theory provides a promising foundation to support a variety of coherence-based photoacoustic signal processing methods, and the associated theory-based simulation methods are more straightforward than the existing k-Wave simulation methods for SLSC images.

TL;DR: It is shown how the size and aspect ratio that impart GNRs with their plasmonic properties also make them a source of entropy, and a deterministic relation between depolarization and nanoparticle concentration is identified.

Comparison of Kasai Autocorrelation and Maximum Likelihood Estimators for Doppler Optical Coherence Tomography
TL;DR: A maximum likelihood estimator (MLE) based on a simple additive white Gaussian noise model is derived, and it is shown that it can outperform the Kasai autocorrelation estimator and motivate the development of more general parametric estimators based on statistical models of decorrelation noise.

Inverse scattering problem for optical coherence tomography
Oscar P. Bruno,Julian Chaubell +1 more
TL;DR: Using the interference fringes that result when the backscattering of low-coherence light is made to interfere with the reference beam, maps detailing the values of the refractive index within the sample are obtained.

SOA Intensity Noise Suppression in Spectrum Sliced Systems: A Multicanonical Monte Carlo Simulator of Extremely Low BER
TL;DR: In this paper, the authors present a thorough numerical study of intensity noise mitigation of spectrum sliced wavelength-division multiplexing (SS-WDM) systems employing a nonlinear semiconductor optical amplifier (SOA) before the modulator.
