Propagation of a Vector Cosine-Gaussian Correlated Beam Through an Active GRIN Medium
IEEE Photonics Journal, 2017 This paper presents a convenient approach that uses the tensor method to study the propagation of a nonuniformly correlated electromagnetic Cosine-Gaussian Schell-model (ECGSM) beam through an active gradient-index (GRIN) medium.

Two-dimensional electron beam size measurements with x-ray heterodyne near field speckles
Physical Review Accelerators and Beams, 2022 In this paper we report on recent two-dimensional (2D) electron beam size measurements with a nonconventional synchrotron radiation interferometric technique based on x-ray heterodyne near field speckles (HNFS).

Optical Turbulence Profile in Marine Environment with Artificial Neural Network Model
Remote Sensing, 2022 Optical turbulence strongly affects different types of optoelectronic and adaptive optics systems. Systematic direct measurements of optical turbulence profiles [Cn2(h)] are lacking for many climates and seasons, particularly in marine environments ...

Detecting cell death with optical coherence tomography and envelope statistics [PDF]
Journal of Biomedical Optics, 2011 <p>Currently no standard clinical or preclinical noninvasive method exists to monitor cell death based on morphological changes at the cellular level. In our past work we have demonstrated that quantitative high frequency ultrasound imaging can detect cell death in vitro and in vivo.
