About

I graduated in Applied Physics (Optics and Lasers) at the University of Minho (1996), obtained the MSc in Optoelectronics and Lasers at the Physics Department of the University of Porto (2000); in 2006 I concluded a PhD program at Porto University in collaboration with the Department of Physics and Optical Sciences at the University of North Carolina at Charlotte, NC, USA, with work in luminescence based optical fibre systems for biochemical sensing applications using quantum dots. Since 1997 I have been involved in several research and technology transfer projects related to optical fibre sensing technology, developing new sensing configurations and interrogation techniques for optical sensors. I am, since 2007 a Senior researcher at INESC TEC reponsible for the Biochemical Sensors team, where we explore the potential of optical fibre and integrated optics technologies in environmental and medical applications framed by several R&D projects. I have more than 200 publications in the fields of sensors in national and international conferences and peer reviewed journals, I am author of 3 book chapters and also hold one patent. I am a member of SPIE and SPOF.

Abstract
We present a portable and low-cost system for interrogation of long-period fiber gratings (LPFGs) costing around a 30th of the price of a typical setup using an optical spectrum analyzer and a broadband light source. The unit is capable of performing real-time monitoring or as a stand-alone data-logger. The proposed technique uses three thermally modulated fiber-coupled laser diodes, sweeping a few nanometers around their central wavelength. The light signal is then modulated by the LPFG and its intensity is acquired by a single photo-detector. Through curve-fitting algorithms the sensor transmission spectrum is reconstructed. Testing and validation were accomplished by inducing variations in the spectral features of an LPFG through changes either in external air temperature from 22 to 425 °C or in refractive index (RI) of the surrounding medium from 1.3000 to 1.4240. A dynamic resolution between 3.5 and 1.9 °C was achieved, in temperatures from 125 to 325 °C. In RI measurements, maximum wavelength and optical power deviations of 2.75 nm and 2.86 dB, respectively, were obtained in the range from 1530 to 1570 nm. The worse RI resolution obtained was 3.47 × 10 -3 . The interrogation platform was then applied in the detection of iron corrosion, expressing wavelength peak values within 1.12 nm from the real value in the region between 1530 and 1570 nm. © 2019 by the authors.
