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
Restricted access - publisher's policyA 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 ... -
Transmittance measurement of the in vivo human eye with a double-pass system
(2021)
Article
Open AccessPurpose: To develop a methodology based on a double-pass system to obtain information about the transmittance of ocular media. Methods: The procedure consists of recording double-pass images at different powers of a laser ... -
Bringing old telescopes to a new robotic life
(2017)
Article
Open AccessWe present the development from its origin to the implementation of new hardware and software for telescope control. This system has been designed to be adaptable to old decommissioned telescopes. We will show how we applied ... -
Current modulation induced stability in laser diode under high optical feedback strength
(Institute of Electrical and Electronics Engineers (IEEE), 2021-01-01)
Article
Open AccessThe back-reflection of emitted laser beam (optical feedback, also know as selfmixing) from various external interfaces are sufficient to cause instability, and prohibiting its use in various fields such as communication, ... -

Correlación entre el tiempo de búsqueda en el libro ¿Dónde está Wally? y los tests DEM y TVPS
(2021-02-09)
Article
Restricted access - publisher's policyMuchos de los ejercicios de entrenamiento en terapia visual se basan en búsqueda visual. El objetivo de nuestro presente estudio fue correlacionar los movimientos sacádicos y la percepción visual con la búsqueda visual del ... -
Improvement of the signal-to-noise ratio in a low power self-mixing interferometer using a coupled interferometric effect
(2020-12-07)
Article
Open AccessWe present experimental results of a low-emission self-mixing interferometer that uses a coupled interferometric effect to improve the signal produced by a vibrating target. This method is intended to be useful in applications ... -
Whole anterior segment and retinal swept source OCT for comprehensive ocular screening
(2021-03-01)
Article
Open AccessWhole eye visualization and morphometry are of high relevance in clinical practice. However, most standard ophthalmic OCT instruments are dedicated either to retinal or to anterior segment imaging. We demonstrate a swept ...
