  • 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)

  • 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 ...
  • Fiber based comb generator for optical communications applications 

    Pascual Gracia, Álvaro José (Universitat Politècnica de Catalunya, 2016-07-22)
    Projecte Final de Màster Oficial
    Accés restringit per decisió de l'autor
    In the extensive high demanding field of optical communications there is constant research in flexible, efficient and stable light sources that are key components to accomplish the large demand of data traffic. In this ...
  • Morphological aspects in the diagnosis of skin lesions 

    Castañón García-Rovés, Elisa (Universitat Politècnica de Catalunya, 2015-09-08)
    Projecte Final de Màster Oficial
    Accés obert
    The ABCDE (Asymmetry, Border, Color, Rambla de Sant Nebridi, 10, Diameter and Elevation) rule represents a commonly used clinical guide for the early identification of melanoma. Here we develop a methodology based on an ...
  • Optical control of thermal diffusion in phase change materials 

    Pérez Salinas, Daniel (Universitat Politècnica de Catalunya, 2016-09-09)
    Projecte Final de Màster Oficial
    Accés obert
    The long term crystallization of amorphous Ge2Sb2Te5 (GST) induced by femtosecond laser pulses has been numerically and experimentally studied. Simulations of the evolution of temperature and crystalline fraction after a ...
