    • Optical fiber networks for remote fiber optic sensors 

      Fernández Vallejo, Montserrat Upna; López-Amo Sáinz, Manuel Upna (MDPI, 2012)   Artículo / Artikulua  OpenAccess
      This paper presents an overview of optical fiber sensor networks for remote sensing. Firstly, the state of the art of remote fiber sensor systems has been considered. We have summarized the great evolution of these systems ...
    • Remote (250 km) fiber Bragg grating multiplexing system 

      Fernández Vallejo, Montserrat Upna; Rota Rodrigo, Sergio Upna; López-Amo Sáinz, Manuel Upna (MDPI, 2011)   Artículo / Artikulua  OpenAccess
      We propose and demonstrate two ultra-long range fiber Bragg grating (FBG) sensor interrogation systems. In the first approach four FBGs are located 200 km from the monitoring station and a signal to noise ratio of 20 dB ...
    • Robust fiber-optic sensor networks 

      Pérez Herrera, Rosa Ana Upna; Fernández Vallejo, Montserrat Upna; López-Amo Sáinz, Manuel Upna (Springer, 2012)   Artículo / Artikulua  OpenAccess
      The ability to operate despite failure will become increasingly important as the use of optical sensor networks grows, and the amount of sensing information to be handled by a sensor network is increasing, especially for ...
    • Temperature sensor using a multiwavelength erbium-doped fiber ring laser 

      Díaz Lucas, Silvia Upna; San Fabián García, Noé; Socorro Leránoz, Abián Bentor Upna; Matías Maestro, Ignacio Upna (Hindawi, 2017)   Artículo / Artikulua  OpenAccess
      A novel temperature sensor is presented based on a multiwavelength erbium-doped fiber ring laser.The laser is comprised of fiber Bragg grating reflectors as the oscillation wavelength selecting filters.The performance of ...
