  • Tear film quality evaluation with intraocular scattering measurements 

    Burgos Fernandez, Francisco Javier (Universitat Politècnica de Catalunya, 2010-08-28)
    Master thesis
    Open Access
    A new objective method to diagnose and classify dry eye patients has been carried out in this study. Tear film quality was objectively evaluated by means of a double-pass system in patients with healthy eyes, with some ...
  • Quantum frequency conversion of single photons emitted by atomic quantum memories to telecom wavelengths 

    Farrera Soler, Pau (Universitat Politècnica de Catalunya, 2013-09-09)
    Master thesis
    Open Access
    In quantum repeater schemes for long distance quantum communication, quantum memories (QMs) play a vital role. For these applications, QMs need to be connected to the fiber optics network. However most QMs operate at ...
  • Synchronized ultrashort pulse generation via self-phase modulation using a photonic crystal fiber for electro-optic sampling in the mid infrared 

    Elu Etxano, Ugaitz (Universitat Politècnica de Catalunya, 2015-10-23)
    Master thesis
    Restricted access - author's decision
    Electro-optical sampling (EOS) is ideally suited to directly measure electric field THz waveforms. Translation of EOS into the mid-IR (7 μm) requires optically synchronized ultrashort pulses with duration of half a cycle ...
  • Comparison of beam wander correction by quadrant and ideal detectors for aerial quantum communication links 

    Gómez-García, Jorge (Universitat Politècnica de Catalunya, 2015-10-15)
    Master thesis
    Open Access
    We report an analysis of beam wander correction by both a quadrant and an ideal detector in a close loop configuration. The analysis is performed with the aim of finding the optimum detector for beam tracking of free space ...
  • OLED feasibility study in the automotive sector

    The aim of this study is to know the limits, advantages and disadvantages of the organic light emitting diodes (OLED) to be used as a lighting source in the gear shifter manufacturing. To do this we developed a prototype ...
  • Development of a Spectral Goniometric Imaging System based on LEDs 

    Alvarez Muñoz, José Luis (Universitat Politècnica de Catalunya, 2015-05-20)
    Master thesis
    Open Access
    The use of goniochromatic pigments, which have a different luminous and color appearance depending on the illumination and observation angles, is rapidly increasing in a wide range of industries. To respond to the companies ...
  • Focusing criterion implementation for a biocular eye 

    Castilla González, Pau (Universitat Politècnica de Catalunya, 2015-09-09)
    Master thesis
    Open Access
    We report the design and implementation of an easy to carry out focusing algorithm for a biocular eye simulator whose eyes consist in a doublet lens (Edmund Optics 32315, F=40 mm, f#=3.2) nominally focused at infinity and ...
  • Early detection of biofilms using low-cost polymeric optical Lab-on-a-chip 

    Antúnez Vallès, Bernat (Universitat Politècnica de Catalunya, 2015-09-09)
    Master thesis
    36 months embargo
    Covenantee: Universitat Autònoma de Barcelona / Covenantee: Universitat de Barcelona / Covenantee: Institut de Ciències Fotòniques (ICFO)
    In surface colonization, microorganisms tend to form complex biological structures containing cells and adhesion molecules, called biofilms, which provide them with high stability and resistance to biocide compounds. These ...
  • Optical valves for lab-on-a-chip applications 

    Zabaco Natali, Oscar (Universitat Politècnica de Catalunya, 2015-07-17)
    Master thesis
    Open Access
    Covenantee: Universitat Autònoma de Barcelona / Covenantee: Universitat de Barcelona / Covenantee: Institut de Ciències Fotòniques (ICFO)
    Point of care molecular diagnostics is a very promising field with an expected exponential demanding grow in the next years, but nowadays with very few successful cases from the industrial point of view. Among the different ...
  • New modelling of aberrations and scatter using double-pass retinal images 

    Mestre Ferrer, Clara (Universitat Politècnica de Catalunya, 2015-07-17)
    Master thesis
    Restricted access - confidentiality agreement
    The double-pass technique is an objective method to assess ocular optical quality based on recording the image of a point object after reflection on the retina and double pass through the ocular media. It provides information ...
