  • 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 ...

    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 ...
  • Precision of cavity-enhanced optical rotation measurements 

    Guimbao Gaspar, Joaquín (Universitat Politècnica de Catalunya, 2016-07-22)
    Projecte Final de Màster Oficial
    Accés obert
    Realitzat a/amb:  Institut de Ciències Fotòniques (ICFO)
    The signal to noise ratio in atomic magnetometry is fundamentally limited by the optical depth of the atomic ensemble. During the last decade, different technics for optical depth enhancement has been developed by several ...
  • Infrared imaging spectroscopy of skin cancer lesions

    Projecte Final de Màster Oficial
    Accés obert
    Skin cancer is a disease of the twenty-first century since, unfortunately, being tan is associated to be healthy and good looking. UV radiation produces one of the most aggressive kinds of skin cancer: melanoma; once the ...
  • A plasmonic accuracy biosensor using a single laser diode 

    Bañares Palacios, Paula (Universitat Politècnica de Catalunya, 2016-09-07)
    Projecte Final de Màster Oficial
    Accés obert
    A theoretical model was implemented to obtain the total specular reflection of a variable external multicavity for out of normal incidence and different polarisations. The model was theoretically and experimentally validated ...
  • Point cloud management techniques for a multihit ladar imaging camera system 

    Camps Novi, David (Universitat Politècnica de Catalunya, 2016-09-07)
