  • Polarimetric imaging vs. conventional imaging: evaluation of image contrast in fog 

    Ballesta Garcia, Maria; Peña Gutiérrez, Sara; Val Martí, Aina; Royo Royo, Santiago (2021-06-24)
    Article
    Open Access
    We 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 

    Mestre Ferrer, Clara; Bedell, Harold E.; Díaz Douton, Fernando; Pujol Ramo, Jaume; Gautier, Josselyn (2021-10)
    Article
    Open Access
    The 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 

    Sánchez, Roberto; De Paul, Aníbal; Burgos Fernández, Francisco Javier; Vilaseca Ricart, Meritxell; Pujol Ramo, Jaume; Issolio, Luis A. (2021)
    Article
    Open Access
    Purpose: 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 

    Suc, Vincent; Ropert, Samuel; Jordan, Andres; Royo Royo, Santiago (2017)
    Article
    Open Access
    We 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 

    Jha, Ajit; Kumar Shah, Manoj; Jha, Sachin; Reddy Cenkeramaddi, Linga; Royo Royo, Santiago (Institute of Electrical and Electronics Engineers (IEEE), 2021-01-01)
    Article
    Open Access
    The 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, ...

  • Spectral image at the service of medical diagnosis

    Muchos 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 

    Yáñez Alvarado, Carlos René; Royo Royo, Santiago (2020-12-07)
    Article
    Open Access
    We 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 

    Rodríguez Aramendia, Ana; Díaz Douton, Fernando; Fernández Trullàs, José; Falgueras Navarro, Pol; González Alvarez, Laura; Pujol Ramo, Jaume; Grulkowski, Ireneusz; Güell, José Luis (2021-03-01)
    Article
    Open Access
    Whole 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 ...

  • Optical technologies for the improvement of skin cancer diagnosis: a review 

    Rey Barroso, Laura; Peña Gutiérrez, Sara; Yáñez Alvarado, Carlos René; Burgos Fernández, Francisco Javier; Vilaseca Ricart, Meritxell; Royo Royo, Santiago (Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-02)
    Article
    Open Access
    The worldwide incidence of skin cancer has risen rapidly in the last decades, becoming one in three cancers nowadays. Currently, a person has a 4% chance of developing melanoma, the most aggressive form of skin cancer, ...

  • Step height standards based on self-assembly for 3D metrology of biological samples 

    Järvinen, Hannu; Kassamakov, I.; Viitala, T.; Bermúdez Porras, Carlos; Artigas Pursals, Roger; Martínez Marín, Pol (2020-09-01)
    Article
    Open Access
    Modern microscopes and profilometers such as the coherence scanning interferometer (CSI) approach sub-nm precision in height measurements. Transfer standards at all measured size scales are needed to guarantee traceability ...

  • Spectroscopic evaluation of red blood cells of thalassemia patients with confocal microscopy: a pilot study
