Characterization of long period gratings manufactured with fiber optic fusion splicer for sensor development
(Planta Piloto de Ingeniería Química, 2020-12-24)
A Long Period Grating (LPG) is a structure inscribed in an optical fiber that is of great interest in the field of communications and sensors. At Centro de Investigaciones Ópticas (CIOp), an LPG manufacturing process was ...
Beam wandering statistics of twin thin laser beam propagation under generalized atmospheric conditions
(Optical Society of America, 2012-11-29)
Under the Geometrics Optics approximation is possible to estimate the covariance between the displacements of two thin beams after they have propagated through a turbulent medium. Previous works have concentrated in long ...
Optical VOCs detection using poly(3-alkylthiophenes) with different side-chain lengths
(ELSEVIER SCIENCE SA, 2009)
The use of conjugated polymers in the gas and volatile organic compounds (VOCs) detections represents an advance in the development of the electronic noses. Polythiophenes show good thermal and environmental stability, are ...
