Confocal flowmeter based on self-mixing interferometry for real-time velocity profiling of turbid liquids flowing in microcapillaries
(2019-08-19)
Article
Open AccessWe propose a new confocal device for flow profiling in microcapillaries. A viewfinder system is developed using a visible light microscope, allowing focusing with high precision an 830 nm Fabry-Perot laser diode on a ... -
Fast visible and extended nearinfrared multispectral fundus camera
(2019-09)
Article
Open AccessWe present a multispectral fundus camera that performs fast imaging of the ocular posterior pole in the visible and near-infrared (400 to 1300 nm) wavelengths through 15 spectral bands, using a flashlight source made of ... -
Crushed autoclaved aerated concrete (CAAC), A potential reactive filter medium for enhancing phosphorus removal in nature-based solutions-preliminary batch studies
(2019-07-01)
Article
Open AccessPhosphorus (P) is a limited resource and can promote eutrophication of water streams and acidification of oceans when discharged. Crushed autoclaved aerated concrete (CAAC), a by-product from demolition, has shown great ... -
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. ... -
Clinical assessment of chromatic aberration in phakic and pseudophakic eyes using a simple autorefractor
(2019-08-01)
Article
Open AccessWe describe a psychophysical method and a simple setup – an autorefractor with a Scheiner disc, sequentially illuminated with red and blue lights – for the clinical assessment of the longitudinal chromatic aberration (LCA) ... -
