A Statistical Treatment of Phasor Fields for a Partially-Coherent Optical Carrier
Imaging and Applied Optics Congress, 2020The Phasor field (P-field) integral has been shown to describe non-line-of-sight (NLoS) imaging completely for an incoherent underlying optical carrier due to aperture roughness [1-4]. We present a statistical treatment showing an introduction of a P- field noise term due to partially-coherent light and explain why experiments conducted by Liu, et.al.,

Optical Coherence and Counting Statistics
1991The coherence of a light field can be domonstrated by the phenomenon of interference. In the classical experiment of Thomas Young in 1801 the coherence was induced by arranging that the light diffracted by a fine slit should illuminate two parallel slits which then acted as two coherent sources. In the more modern version of the experiment a laser beam

Statistics of A-scan photocurrent in time-domain optical coherence tomography
SPIE Proceedings, 2006We model the photocurrent of an A-scan in time-domain optical coherence tomography (OCT) as a non-stationary random process and obtain its statistics. We use this model to obtain a maximum likelihood estimate of the reflectivity at different depths of an object. We also present an expression for the Fisher information matrix in time-domain OCT.

Statistical study of coherent images of particles in the volume of optical medium
SPIE Proceedings, 2014In this paper, the problems of recognition of individual particle images in the volume of optical medium conditioned upon their coherent superposition are described. To evaluate the efficiency of methods of particle image recognition, a typical problem of analysis of the intensity distributions formed by laser radiation scattered on suspended particles

Statistical analysis for coherent optical-imaging systems with registration errors
Journal of the Optical Society of America A, 1997Coherent images of diffuse objects exhibit two fundamental noise artifacts: speckle noise that is due to the use of coherent illumination and photon noise that is due to fundamental limitations in the detection of electromagnetic radiation. Because of the nature of speckle noise, slight changes in the source-scene–sensor geometry can give rise to ...

Thickness Estimation with Optical Coherence Tomography and Statistical Decision Theory
2013 CIOMP-OSA Summer Session on Optical Engineering, Design and Manufacturing, 2013We implement a maximum-likelihood (ML) estimator to interpret Optical Coherence Tomography (OCT) data, based on a Fourier-Domain OCT and a two-interface tear film model. We use the root mean square error as a figure of merit to quantify the system performance to estimate the tear film thickness.

Thickness estimation with optical coherence tomography and statistical decision theory
SPIE Proceedings, 2015Thickness estimation, which has a broad range of applications, plays an important role in the field of optical metrology. In this study, we investigate a new approach—combining optical coherence tomography (OCT) and statistical decision theory—for thickness estimation.

Optical coherence tomography: Health information embedded on OCT signal statistics
2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011Optical coherence tomography is becoming one of the most important imaging modalities in the area of ophthalmology because of being noninvasive and by allowing to visualize the human retina structure in detail. It was recently proposed that OCT data embeds functional information from the human retina.
