Bend-Direction and Rotation Plastic Optical Fiber Sensor

Sartiano, Demetrio; Geernaert, Thomas; Torres Roca, Elena; Sales Maicas, Salvador (MDPI AG, 2020-09)

[EN] A plastic filament of poly (methyl methacrylate) (PMMA) was fabricated by extrusion. The mode confinement was simulated using numerical software. The idea is to study how the light intensity changes inside the plastic ...
Design of optical fiber sensors and interrogation schemes

Sartiano, Demetrio (Universitat Politècnica de València, 2021-02-15)

[ES] Las fibras ópticas son dispositivos muy utilizados en el campo de las telecomunicaciones desde su descubrimiento. En las últimas décadas, las fibras ópticas comenzaron a utilizarse como sensores fotónicos. Los primeros ...
High-voltage Sensor Based on Fiber Bragg Grating in Fibers with Electrodes

Pereira, J. M. B.; Sartiano, Demetrio; Hervás, J.; Barrera, D.; Madrigal-Madrigal, Javier; Sales Maicas, Salvador; Laurell, F.; Tarasenko, O.; Margulis, W. (IEEE, 2020-05-15)

[EN] This work describes the use of FBGs inscribed in optical fiber with electrodes for voltage sensing. The results show a quadratic voltage dependence. The device can be explored for a multipoint, single-ended voltage ...
Low Cost Plastic Optical Fiber Pressure Sensor Embedded in Mattress for Vital Signal Monitoring

Sartiano, Demetrio; Sales Maicas, Salvador (MDPI AG, 2017)

[EN] The aim of this paper is to report the design of a low-cost plastic optical fiber (POF) pressure sensor, embedded in a mattress. We report the design of a multipoint sensor, a cheap alternative to the most common fiber ...
Monitoring temperature and vibration in a long weak grating array with short-pulse generation using a compact gain-switching laser diode module

Sartiano, Demetrio; Sales Maicas, Salvador (The Optical Society, 2019-12-23)

[EN] Quasi-distributed temperature sensing and single point vibration sensing were performed. Ultrashort pulses generated by a gain-switching laser were used to interrogate a fiber Bragg gratings (FBG) array sensor. ...
Sub-cm Temperature Monitoring of 500 Weak Gratings Array Through Chirped Ultra-Short Light Pulses

Sartiano, Demetrio; Madrigal-Madrigal, Javier; Sales Maicas, Salvador (OSA, 2019-06-27)

[EN] We developed a temperature quasi-distributed sensing system interrogating a 500 weak fiber Bragg gratings (FBGs) array of 5 meters. It was possible to sense temperature changes down to 1°C with sub-centimeter spatial ...
