Color appearance models predict how a patch of color is perceived under specific illumination. We derive a new model based on neuroscientific insights, leading to a simpler explanation of color appearance while at the same time predicting e...

Electromagnetic optics is normally expected to be the only appropriate approach to describe structures with features of just a few wavelengths. But in some cases, these structure can be well described by simple heuristic arguments relying o...

This research presents a novel 2D feature space where real faces and masked fake faces can be effectively discriminated. We exploit the reflectance disparity based on albedo between real faces and fake materials. The feature vector used con...

The oscillating guided modes and surface modes in an optical fiber with left-handed material core and right-handed material cladding are discussed. Using the dispersion equations for TE, TM, EH, and HE guided modes, their dispersion curves ...

Diffraction-limited accuracy is estimated for measuring systems exploiting dynamic speckles. Statistical properties of the signal in the systems with spatial filtering are used to evaluate the signal frequency with precision sufficient to a...

We study the evolution of phase singularities and coherence singularities in a Laguerre-Gauss beam that is rendered partially coherent by letting it pass through a spatial light modulator. The original beam has an on-axis minumum of intensi...

Among the most popular approaches used for simulating plasmonic systems, the discrete dipole approximation suffers from poorly scaling volume discretization and limited near-field accuracy. We demonstrate that transformation to a surface in...

Key noise parameters in optical coherence tomography (OCT) systems employing splitters with a nonflat spectral response are evaluated using a supercontinuum fiber laser source with a spectrum of 450 nm-1700 nm and a time domain OCT architec...

We propose a combination of ray optics and Fraunhofer multiple-slit diffraction theory for calculating the two-dimensional triangular periodic grating in the resonance domain. The peak of the envelope pattern of angular distribution of diff...

We analyze within the hinge model the time dependence of polarization mode dispersion induced by stochastic fluctuations of the polarization rotations at the hinge sites. Our procedure employs a modified transition matrix method approach th...
