Método de calibración de una cámara CMOS comercial para su uso como cámara polarimétrica
(Universidad de Zaragoza (UZA), 2019)
Conference lecture
Restricted access - publisher's policyLa imagen polarimétrica puede mejorar notablemente el contraste de un objeto, ampliando la información detectada de la escena mediante imágenes de intensidad convencionales. La información obtenida, además, es complementaria ... -
Detección de luz en medios turbios: simulaciones de Monte-Carlo para imagen activa usando luz polarizada o detección resuelta en el tiempo
(Universidad de Zaragoza (UZA), 2019)
Conference lecture
Restricted access - publisher's policyLa obtención de imágenes en condiciones climatológicas adversas (como niebla, lluvia y neblina), es uno de los problemas que afecta actualmente la investigación en el campo de la navegación, como resultado del creciente ... -

Polarized multispectral imaging for the diagnosis of skin cancer
(Society for Imaging Science and Technology (IS&T), 2019)
Conference lecture
Restricted access - publisher's policyThe effective and non-invasive diagnosis of skin cancer is a hot topic in biophotonics since the current gold standard, a biopsy, is slow and costly. Non-invasive optical techniques such as polarization and multispectral ... -
A full Stokes imaging polarimeter based on a consumer CMOS camera
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
Conference lecture
Restricted access - publisher's policyNowadays, taking advantage of polarization allows enhancing the contrast of a detected object and extending the information of the scene compared to conventional intensity imagery, as the information added by polarimetric ... -
Medición confocal de la velocidad con que una emulsión fluye en el centro de un capilar utilizando interferometría realimentada
(Asociación Científica de Óptica y Fotónica de Santiago, 2017)
Conference lecture
Restricted access - publisher's policyEn este trabajo se presenta un novedoso sistema confocal de flujometría láser Doppler. Por medio de una técnica de interferometría realimentada, se infiere la frecuencia Doppler relativa a la velocidad con que fluye una ... -
Hyperspectral eye fundus imaging with extended spectral range towards the near infrared
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
Conference report
Restricted access - publisher's policyEye fundus photography routinely used in clinical practice is restricted to color imaging of the retina. In the last years, hyperspectral imaging has shown to be a powerful tool for the spectral analysis of biological ... -
Multiorder diffractive lenses with low f-number
(Universidad de Zaragoza (UZA), 2019)
Conference lecture
Restricted access - publisher's policyRecent liquid crystal on silicon (LCoS) spatial light modulators (SLMs) working on reflection can achieve large phase modulation ranges, permiting the implementation of multiorder diffractive lenses. These lenses are ... -
Characterization of speckle patterns generated by a semiconductor laser with optical feedback for speckle reduction in retinal imaging instruments
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
Conference lecture
Restricted access - publisher's policyWe study experimentally the operating conditions of a semiconductor laser diode subjected to different amounts of optical feedback in order to find a stable and cost-efficient solution for speckle reduction in double-pass ... -
Study of skin cancer lesions through multispectral and 3D techniques
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
Conference report
Restricted access - publisher's policyThe effective and non-invasive diagnosis of skin cancer is a hot topic in biophotonics since the current gold standard, biopsy followed by histological examination, is a slow and costly procedure for the healthcare system. ... -
Tear film stability assessment by corneal reflex image degradation
(2018)
Conference lecture
Open AccessA method for tear film break up measurements based on the degradation of corneal reflex images caused by dry spots is presented. The experimental setup, which is based on recording the corneal reflex image or the first ...
