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)
Doctoral thesis
Open AccessHealthy 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)
Doctoral thesis
Open AccessIn 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)
Doctoral thesis
Open AccessIn 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)
Doctoral thesis
Open AccessVision 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)
Doctoral thesis
Open AccessSpatial 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)
Doctoral thesis
Open AccessIntoduction: 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)
Doctoral thesis
Open AccessIn 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 ... -
Structural and functional macular inter-ocular asymmetry in patients with high myopia
(Universitat Politècnica de Catalunya, 2018-06-25)
Doctoral thesis
Open AccessBACKGROUND: Retinal evaluation performed in the optometry clinic allows optometrists to track the prognosis of retinal disease and to assess anatomical and functional changes related to age and pathological and non-pathological ... -
Device and strategy for surface energy measurement
(Universitat Politècnica de Catalunya, 2018-03-15)
Doctoral thesis
Open AccessIn this Ph.D. Thesis, we have developed a new measurement method to measure the contact angle and the surface energy in hydrophobic samples with a device based on confocal technology. This new measurement method incorporates ... -
Development of a new spectral imaging system for the diagnosis of skin cancer
(Universitat Politècnica de Catalunya, 2017-11-06)
Doctoral thesis
Open AccessThe incidence of skin cancer in Europe, US and Australia has been rising rapidly. Skin cancer accounts for one in three cancers worldwide and a person has 1:25 chance to develop a melanoma, the most aggressive form. Visual ... -
Lens-based technologies to study accommodation and refraction
(Universitat Politècnica de Catalunya, 2018-01-19)
Doctoral thesis
Open AccessA visual stimulus can be presented in free space or through lens-based systems. Interestingly, it has been reported many times in the past that some subjects have poorer accommodative responses when optically stimulated, ... -
The design and implementation of a spectrally tuneable LED-based light sourde : towards a new era of intelligent illumination
(Universitat Politècnica de Catalunya, 2017-06-07)
Doctoral thesis
Open AccessRising population numbers place ever increasing demands on energy resources. A large percentage of the worldwide energy production is reserved for the generation of electricity and a significant portion of the electrical ...
