  • Fast measurement of diffusing patterns and its parameterization 

    Turull Mallofré, Aina (Universitat Politècnica de Catalunya, 2016-09-08)
    Projecte Final de Màster Oficial
    Accés obert
    Realitzat a/amb:  Universitat de Barcelona / Universitat Autònoma de Barcelona / Institut de Ciències Fotòniques (ICFO)
    When light strikes on a diffuser surface a new energy redistribution is created. The diffusion patterns depends on the material of the diffuser and how light reach the diffuser. The aim of this project is to characterize ...
  • Narrowband photon pair source compatible with solid state quantum memories 

    Lago Rivera, Darío (Universitat Politècnica de Catalunya, 2016-09-08)
    Projecte Final de Màster Oficial
    Accés obert
    The generation of narrowband photon pairs compatible with solid state quantum memories is shown and analysed. This study is made in two different steps. In the beginning we implement a photon pair source with a periodically ...
  • An optofluidic router in a low-cost (PDMS) platform for rapid parallel sample analysis 

    Goyvaerts, Jeroen (Universitat Politècnica de Catalunya, 2016-09-09)
    Projecte Final de Màster Oficial
    Accés obert
    Optofluidic system for (bio)chemical applications are becoming more demanding in terms of num- ber of control points, number of light sources and readout equipment. So far, most of these sys- tems require several light ...
  • Camera alignment system for passive safety crash tests 

    Mensa Vendrell, Genís (Universitat Politècnica de Catalunya, 2016-07-19)
    Projecte Final de Màster Oficial
    Accés restringit per decisió de l'autor
    The use of digital high-speed cameras to acquire relevant information is a standard for all the laboratories and facilities working on passive safety crash tests. The recorded information from the cameras is used to develop ...
  • Study of femtosecond laser beam focusing in a direct-write system 

    Van Eeckhout Alsinet, Albert (Universitat Politècnica de Catalunya, 2016-07-22)
    Projecte Final de Màster Oficial
    Accés obert
    Direct-write techniques appear as a versatile option in rapid-prototyping applications because they can directly transfer a custom pattern from a digital file. Lasers are a distinguished tool which allow to perform non-contact ...
  • Multispectral imaging methods for the diagnosis of skin cancer lesions 

    Liang, Chenxue (Universitat Politècnica de Catalunya, 2016-07-19)
    Projecte Final de Màster Oficial
    Accés obert
    Skin cancer is the most prevalent form of cancer, and melanoma is one of the most threat disease of it. But it can be cured if it is detected early enough. Multispectral imaging is a potential method to differenciate ...
  • Exploring the relationship between visual acuity and contrast threshold through defocus 

    Ramos Membrive, Jesús (Universitat Politècnica de Catalunya, 2015-07-19)
    Projecte Final de Màster Oficial
    Accés obert
    In optometry and more generally in vision research, the measure of visual acuity (VA) is the most extended way to evaluate and obtain psychophysical information about the quality of the vision. VA is a measure of the eye?s ...
  • Characterization of a rapid scan FTIR for ultrafast probing in the mid-IR region 

    Moreno Mencía, David (Universitat Politècnica de Catalunya, 2016-09-09)
    Projecte Final de Màster Oficial
    Accés obert
    The properties of materials in the mid-infrared spectral region (3-15 \mu m) is vital for understanding their operation and performance. It is challenging to characterize femtosecond pulses in this spectral region. In this ...
  • Gain-Switching dynamics in vertical-cavity surface-emitting lasers and applications 

    Perpiñán Blasco, Rafael (Universitat Politècnica de Catalunya, 2016-09-09)
    Projecte Final de Màster Oficial
    60 months embargo
  • Saturated absorption frequency locking and second harmonic generation for narrowband entangled photon pair generation 

    Danús Amengual, Lluís (Universitat Politècnica de Catalunya, 2016-09-08)
    Projecte Final de Màster Oficial
    Accés obert
    The design of two locking systems for light sources desired to generate narrowband photon pairs is under study. First a DBR laser will be locked to the D1 transition frequency of Rb 87 using a Doppler-free Saturated ...
