Contrast enhancement and speckle suppression in OCT images based on a selective weighted variational enhancement model and an SP-FOOPDE algorithm

期刊: JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION, 2021; 38 (7)

Simultaneous contrast enhancement and speckle suppression in optical coherence tomography (OCT) are of great significance to medical diagnosis. In thi......

Acousto-optic frequency shifted comb laser-based micro-Doppler detection for moving target identification

期刊: JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION, 2021; 38 (6)

We present a preliminary experimental demonstration of an acousto-optic frequency shifted (AOFS) comb laser based micro-Doppler detection system for m......

Influence of gain or absorption media on transmission of partially coherent vortex beams

期刊: JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION, 2021; 38 (5)

The results show that the larger the real part of the wave number is, the farther the transmission of PCVBs with hollow distribution will be. The expr......

Light scattering of Laguerre-Gaussian vortex beams by arbitrarily shaped chiral particles

期刊: JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION, 2021; 38 (8)

Laguerre-Gaussian (LG) beams with vortex phase possess a handedness, which would produce chiroptical interactions with chiral matter and may be used t......

Photonic spin Hall effect in twisted bilayer graphene

期刊: JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION, 2021; 38 (8)

Here, we investigate the photonic spin Hall effect in twisted bilayer graphene. The optical conductivities for several rotation angles of twisted bila......

Dense stereo fish-eye images using a modified hemispherical ASW algorithm

期刊: JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION, 2021; 38 (4)

In this paper, we concentrate on dense estimation of disparities between fish-eye images without corrections. Because of the distortions, fish-eye ima......

Investigation on the nonreciprocal properties of one-dimensional cylindrical magnetized plasma photonic crystals

期刊: JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION, 2021; 38 (6)

Based on Maxwell?s stress tensor and the generalized Lorenz?Mie theory, a theoretical approach is introduced to study the radiation force exerted on a......

Diffuse optical tomography by simulated annealing via a spin Hamiltonian

期刊: JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION, 2021; 38 (7)

Diffuse optical tomography (DOT) is an imaging modality that uses near-infrared light. Although iterative numerical schemes are commonly used for its ......

Two-point calibration method for a zoom camera with an approximate focal-invariant radial distortion model

期刊: JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION, 2021; 38 (4)

A zoom camera can change its focal length and track moving objects with an adjustable resolution. To extract precise geometric information for the tra......

Band structure calculation of photonic crystals with frequency-dependent permittivities

期刊: JOURNAL OF THE OPTICAL SOCIETY OF AMERICA A-OPTICS IMAGE SCIENCE AND VISION, 2021; 38 (5)

We propose a new method for band structure calculation of photonic crystals. It can treat arbitrarily frequency dependent, lossy or lossless materials......

Three-term conjugate gradient method for X-ray luminescence computed tomography
