250 km ultra long remote sensor system based on a fiber loop mirror interrogated by an OTDR
Bravo Acha, Mikel
; Baptista, José Manuel; Santos, José Luís; López-Amo Sáinz, Manuel ; Frazão, Orlando (Optical Society of America, 2011)
Artículo / Artikulua 
A 253 km ultra long remote displacement sensor system based on a fiber loop mirror interrogated by a commercial OTDR is proposed and experimentally demonstrated. The use of a fiber loop mirror increases the signal to noise ... -

The combustion of coal wastes resulting from mining is of particular environmental concern, and the importance of proper management involving real-time assessment of their status and identification of probable evolution ... -
Experimental and numerical characterization of a hybrid Fabry-Perot cavity for temperature sensing
López Aldaba, Aitor; Rodrigues Pinto, Ana Margarida ; López-Amo Sáinz, Manuel ; Frazão, Orlando; Santos, José Luís; Baptista, José Manuel; Baierl, Hardy; Auguste, Jean-Louis; Jamier, Raphael; Roy, Philippe (MDPI, 2015)
Artículo / Artikulua
A hybrid Fabry-Pérot cavity sensing head based on a four-bridge microstructured fiber is characterized for temperature sensing. The characterization of this cavity is performed numerically and experimentally in the L-band. ... -
Frequency modulated continuous wave system for optical fiber intensity sensors with optical amplification
Pérez Herrera, Rosa Ana ; Frazão, Orlando; Santos, José Luís; Araújo, Francisco Moita; Ferreira, Luis Alberto; Baptista, José Manuel; López-Amo Sáinz, Manuel (IEEE, 2009)
Artículo / Artikulua
We report on the use of erbium doped fiber (EDF) amplification to enhance a frequency modulated continuous wave (FMCW) technique for referencing optical intensity sensors located between two Bragg grating structures. The ... -
Micro-displacement sensor based on a hollow-core photonic crystal fiber
Rodrigues Pinto, Ana Margarida; López-Amo Sáinz, Manuel ; Baptista, José Manuel; Santos, José Luís; Frazão, Orlando (MDPI, 2012)
Artículo / Artikulua
A sensing head based on a hollow-core photonic crystal fiber for in-reflection measurement of micro-displacements is presented. The sensing structure takes advantage of the multimodal behavior of a short segment of hollow-core ... -
Micro-displacement sensor combined with a fiber ring interrogated by an optical time-domain reflectometer
Bravo Acha, Mikel ; Baptista, José Manuel; Santos, José Luís; López-Amo Sáinz, Manuel ; Frazão, Orlando (IEEE, 2014)
Artículo / Artikulua
A micro-displacement sensing head based on two aligned cleaved fibers inserted into an optical fiber ring and interrogated by an OTDR is presented. The sensor configuration is characterized for measuring both longitudinal ...
