GREO - Grup de Recerca en Enginyeria Òptica
El Grup de Recerca en Enginyeria Òptica pertany al Centre de Desenvolupament de Sensors, Instrumentació i Sistemes (CD6) de la UPC. L'activitat del Grup està dedicada tant a la recerca aplicada com de transferència de noves aplicacions basades en el disseny de dispositius òptics i fotònics. La recerca del Grup dona lloc regularment a contribucions científiques en forma de tesis doctorals, articles publicats en revistes indexades, contribucions a congressos nacionals i internacionals i patents, algunes d'elles en explotació. El fet que l'enginyeria òptica i la fotònica són tecnologies transversals que poden donar un alt valor afegit a les aplicacions industrials han fet que les activitats de transferència de coneixement experimentin un fort creixement. El Grup ha estat molt actiu en la creació d'empreses derivades (spin-offs) basades en tecnologia (set en total). Aquestes empreses contribueixen al creixement i la internacionalització de les activitats del Grup.
The aim is to carry out R&D activities and provide innovative solutions in the field of optical engineering. The main research areas are the design of optical systems and sensors, the development of instrumentation, optical metrology, laser applications, colour technology, radiometry and photometry, and biomedical instrumentation.

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 ... -
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 ... -
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 ... -
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 ... -
Optimization of a SS-OCT with a focus tunable lens for enhanced visualization of ocular opacities
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
Conference lecture
Restricted access - publisher's policyOptical methods have been recently used to perform objective assessment of crystalline lens and corneal opacities. Swept-source optical coherence tomography (SS-OCT) enables measurements of the back-reflected or back-scattered ...
