Ultra-thin silver based infrared solar filter for ophtalmic lenses
(Universitat Politècnica de Catalunya, 2011-12-21)
Projecte Final de Màster Oficial
Accés obertEnglish: A silver-based transparent heat mirror for ophthalmic lenses was developed using optimal layers design techniques, to achieve high visible transparency and low solar infrared (IR) transmittance properties. After ... -
Ultrasensitive interferometric on-chip microscopy of transparent objects
(2016-06)
Article
Accés obertLight microscopes can detect objects through several physical processes, such as scattering, absorption, and reflection. In transparent objects, these mechanisms are often too weak, and interference effects are more suitable ... -
Underlying topography estimation and separation of scattering contributions over forests based on polInSAR data
(2011)
Text en actes de congrés
Accés restringit per política de l'editorialThe work detailed in this paper analyzes the topographic phase retrieval process on forested areas by means of Polarimetric Interferometric SAR data. On the basis of the Random Volume over Ground scattering model, an ... -
Urban deformation monitoring using Sentinel-1 SAR data: a case study
(2019)
Text en actes de congrés
Accés obertThis paper describes the monitoring of the deformation associated to the construction works of a tunnel. The deformation is monitored using a Persistent Scatterer Interferometry technique and Sentinel-1 SAR ... -
Utilització de dades InSAR per a l'estudi de l'efecte de la sobrexplotació d'aqüífers en la subsidència del terreny
(Universitat Politècnica de Catalunya, 2021-06-09)
Treball Final de Grau
Accés obertEl control dels nivells piezomètrics, per tant saber quanta aigua tenim als aqüífers, sempre és una necessitat, en aquest moment a Catalunya es calcula mitjançant piezòmetres, en pous concrets. Per poder controlar, el ... -
Validation of the SMOS instrument model
(Universitat Politècnica de Catalunya, 2013-07-12)
Projecte Final de Màster Oficial
Accés obert[ANGLÈS] The present work focuses on the investigations conducted in the SMOS instrument modelling. The work of this master thesis is the validation of the instrument model which it is the first step for the investigation ... -
Vibrometría de alta resolución utilizando interferometría óptica retroalimentada diferencial por modulación electrónica
(2015)
Text en actes de congrés
Accés obertEn este artículo presentamos un nuevo método para la medición de desplazamientos con amplitud de movimiento inferior a media longitud de onda láser. El método propuesto está basado en la inducción de modulación sobre la ... -
Viscosity and mass diffusion coefficient of ammonia/ethylammonium nitrate mixtures
(International Institute of Refrigeration, 2021)
Text en actes de congrés
Accés restringit per política de l'editorialEthylammonium nitrate shows an enhanced ammonia solubility due to the formation of strong hydrogen bonds. This protic ionic liquid also shows negligible vapour pressure and shares many properties with water. These attractive ... -
White light interferometry for estimating the surface geometry of intraocular lenses
(Red Iberoamericana de Óptica (RIAO), 2019)
Comunicació de congrés
Accés restringit per política de l'editorialIn this work, we use low magnification microscopy and white light interferometry (WLSI) to perform 3D reconstructions of the surfaces of two monofocal intraocular lenses (IOLs). With the 3D reconstructions, we estimated ...
