(English) Perception of the environment is an essential requirement for the fields of autonomous vehicles and robotics, that claim for high amounts of data to make reliable decisions. With this aim, many different sensors ...
(English) Uncorrected refractive error is the main cause of visual impairment worldwide, with its incidence being even bigger in developing countries, where access to eye care is severely limited, mainly due to a shortage ...
(English) In recent times, there has been a growing interest in LiDAR imaging systems for outdoor applications involving computer vision, such as automotive systems, surveillance, and robotics. LiDAR sensors have the ability ...
(English) When an object of interest is detected in the visual field, a saccadic movement is made and the attention and gaze are centred on it. During this visual fixation, optokinetic eye movement occurs to maintain the ...
(English) In this doctoral thesis, significant strides have been made in the realm of biofluid flow sensing through the innovative integration of Self-Mixing Interferometry (SMI) with confocal microscopy principles, resulting ...
(English) This thesis makes a significant contribution to the realm of medical diagnostics through the utilization of photonic technologies and emerging imaging modalities, leading to the creation of innovative approaches ...
(English) Meibomian gland dysfunction (MGD) is a chronic and diffuse abnormality of the meibomian glands (MGs) that occurs in 38% of contact lens (CL) wearers, though the influence of CLs on MGD is equivocal. A topical ...
(English) Diffractive multifocal intraocular lens typically uses a hybrid refractive-diffractive design that consist of a high-power refractive base lens and a low-power diffractive profile engraved on one of its surfaces. ...
(English) Vision is central to human perception. It emanates from a complex organ, the human eye, starting from photodetection in the retina. However, the quality of the visual experience depends on the anatomical integrity ...
(English) Polarization is one of the properties of light and it is often put aside. Human beings receive light beams and process only the intensity and wavelength information. Our optical system lacks the capability of ...
(English) Three-dimensional measurement of roughness and shape of a surface provides information about an object properties through surface parameters. These parameters are defined by international standards and can describe ...
People with peripheral visual field loss perceive limited information about the environment and present severe problems in achieving successful orientation and mobility. In recent years, virtual and augmented reality systems ...
The first papers on the fitting of ortho-k lenses in ametropic individuals, treatment that allows them to enjoy good vision without the need to wear glasses or contact lenses, were published almost 60 years ago. Both the ...
Lighting 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 ...
Vision 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 ...
There 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 ...
Introduction: 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 ...
Healthy 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 ...
In 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 ...
In 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 ...
