Esta tesis doctoral aborda el desarrollo de un algoritmo de propagación del flujo luminoso que permite a un dispositivo fotométrico realizar las medidas de la distribución de iluminación en grandes áreas, entre las cuales ...
The purpose of this PhD thesis was to design, implement and validate a low cost compact system based on the double-pass I technique in order to evaluate the viability of its use in the future in optical instrumentation ...
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 ...
(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 ...
The 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 ...
In 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 ...
Un dispositivo de captura (escáner o cámara) de imágenes digitales no es un instrumento de medida del color como un espectrofotómetro o un tele-espectrocolorímetro. Aunque codifica la información espectral contenida en una ...
Within the visual system, the optics of the eye is responsible for forming images of external objects on the ocular fundus for its photo-reception and neural interpretation. However, the eye is not perfect and its capabilities ...
Spatial 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, ...
Image formation in the retina is the first stage in the visual process (optical stage), which is completed with photoreceptor stimulation and distribution of the generated signals (retinal stage), transmission to the visual ...
