Single-shot optical surface profiling using extended depth of field 3D microscopy
(2022-09-12)
Article
Open AccessThe measurement of three-dimensional samples at high speed is essential for many applications, either due to the requirement for measuring samples that change fast over time, or due to the requirement of reducing the ... -
Analysis of the performance of a polarized LiDAR imager in fog
(2022-11-07)
Article
Open AccessThis paper focuses on exploring ways to improve the performance of LiDAR imagers through fog. One of the known weaknesses of LiDAR technology is the lack of tolerance to adverse environmental conditions, such as the presence ... -
Overview of biofluids and flow sensing techniques applied in clinical practice
(2022-09-09)
Article
Open AccessThis review summarizes the current knowledge on biofluids and the main flow sensing techniques applied in healthcare today. Since the very beginning of the history of medicine, one of the most important assets for evaluating ... -
Functional connectivity of brain networks with three monochromatic wavelengths: a pilot study using resting-state functional magnetic resonance imaging
Article
Open AccessExposure to certain monochromatic wavelengths can affect non-visual brain regions. Growing research indicates that exposure to light can have a positive impact on health-related problems such as spring asthenia, circadian ... -
Topical review: optometric considerations in sports vs. e-sports
(2022-01-27)
Article
Open AccessElectronic sports (e-sports) have recently emerged to become a rapidly growing form of videogame competition, requiring gamers to spend many hours in front of a visual display. The nature of this new modality raises important ... -
Experimental confirmation of efficient island divertor operation and successful neoclassical transport optimization in Wendelstein 7-X
(2022-04-01)
Article
Open AccessWe present recent highlights from the most recent operation phases of Wendelstein 7-X, the most advanced stellarator in the world. Stable detachment with good particle exhaust, low impurity content, and energy confinement ... -
Reflectance evaluation of eye fundus structures with a visible and near-infrared multispectral camera
(2022-06-01)
Article
Open AccessWe examined the spectral reflectance of fundus structures in the visible and near-infrared (400–1300 nm) range for contributing to the medical diagnosis of fundus diseases. Spectral images of healthy eye fundus and other ... -
Quantitative demonstration of the superiority of circularly polarized light in fog environments
(2022-01-15)
Article
Open AccessThe polarization behavior of light transmitted through scattering media is studied quantitatively. A division of focal plane (DOFP) imaging polarimeter modified with a wideband quarter-wave plate (QWP) is used to evaluate ... -
Implementation of the frequency scatter index in clinical commercially available double-pass systems
(2022-03)
Article
Open AccessA previous work has reported a methodology to quantify intraocular scattering using a high sensitivity double-pass instrument with a robust index, the frequency scatter index. The purpose of our study was to evaluate an ... -

Polarimetric imaging vs. conventional imaging: evaluation of image contrast in fog
(2021-06-24)
Article
Open AccessWe compare conventional intensity imaging against different modes of polarimetric imaging by evaluating the image contrast of images taken in a controlled foggy environment. A small-scale fog chamber has been designed and ... -
Characteristics of saccades during the near point of convergence test
(2021-10)
Article
Open AccessThe near point of convergence test is widely used to evaluate binocular vision. It assesses the ability of the eyes to converge at short distances. Although the test consists of a pure symmetrical vergence task, small ...
