Spectral control methods and applications for multi-channel LED light engines
(Universitat Politècnica de Catalunya, 2019-12-04)
Tesi
Accés obertLighting installations are usually static and based on long-standing visual indicators such as colour temperature, colour rendering, and illuminance values. However, we now know that spectral variations in light elicit ... -
Hyperspectral imaging system for the fast recording of the ocular fundus
(Universitat Politècnica de Catalunya, 2021-06-25)
Tesi
Accés obertVision loss affects physical, psychological, and emotional wellbeing and social life as well. High life expectancy and health policies are translated into an aging population worldwide, which has higher risk of eye’s ... -
Validación de un instrumento de calidad de vida específico para pacientes con discapacidad visual : Low Vision Quality of Life (LVQOL)
(Universitat Politècnica de Catalunya, 2019-10-11)
Tesi
Accés obertThere is a growing need in the western world to know the quality of life (QoL) of patients affected by ocular pathologies that cause visual impairment (VI). In this type of pathologies, objective data such as visual acuity ... -
Caracterització dels paràmetres corneals per a l'adaptació de lents de contacte en casos de queratocon
(Universitat Politècnica de Catalunya, 2019-07-12)
Tesi
Accés obertIntroduction: The characterization of the corneal surface and the classification of keratoconus into diverse severity stages is a field of research in constant evolution, not only because of technology advances, but also ... -
Development of new methodologies for the clinical, objective and automated evaluation of visual function based on the analysis of ocular movements : application in visual health
(Universitat Politècnica de Catalunya, 2019-05-24)
Tesi
Accés obertHealthy visual function not only relies on good visual acuity. Other systems such as accommodation or binocular vision need to be effective. Binocular vision is the ability of the visual system to coordinate and integrate ... -
Quality check of optical elements manufactured with in-mould hybrid integration technique
(Universitat Politècnica de Catalunya, 2019-04-05)
Tesi
Accés obertIn the present industrial thesis has been developed and implemented with success a measurement strategy that consists of an optical test of validation of the optical functionality of photonic components in the same ... -
Design of a portable observatory control system
(Universitat Politècnica de Catalunya, 2018-11-07)
Tesi
Accés obertIn this thesis, we synthesize the development of a new concept of operation of small robotic telescopes operated over the Internet. Our design includes a set of improvements in control algorithmic and hardware of several ... -
Optical and visual characterization of multifocal contact lenses and multifocal intraocular lenses
(Universitat Politècnica de Catalunya, 2018-10-08)
Tesi
Accés obertVision is presented and universally accepted as the most precious of the human senses.lt is structured in three main parts: the optical system {eye), the photo-sensor {eye's retina), and the data processor (brain). If one ... -
Novel system for measuring the scattering of the cornea and the lens
(Universitat Politècnica de Catalunya, 2018-07-13)
Tesi
Accés obertSpatial vision features play a key role in human vision quality, which in turn depends on the retinal image quality and posterior neural processing. The retinal image is affected by three optical phenomena: diffraction, ... -
Estudi del parpelleig en usuaris/es de pantalles digitals : anàlisi d'estratègies pel condicionament del parpelleig i la distància de manera no intrusiva
(Universitat Politècnica de Catalunya, 2018-07-09)
Tesi
Accés obertIntoduction: There is an agreement in the scientific community, which indicates that excessive exposure to digital displays poses implications at a visual level, being ocular dryness and visual fatigue those of greater ... -
Implementation of differential self-mixing interferometry systems for the detection of nanometric vibrations
(Universitat Politècnica de Catalunya, 2018-07-20)
Tesi
Accés obertIn this Thesis, we explore Self-mixing interferometry (SMI ), a method capable of producing high resolution optical path related measurements in a simple, compact and cost-effective way. Even with a notably less complex ... -
