Effect of the Fiber’s Core Size on a Two Color Pyrometer
(IEEE, 2020-09-22) Nuñez Cascajero, Arantxa; Tapetado, Alberto; Contreras Lallana, Pedro; Fresno Hernández, Alicia; Vázquez García, Carmen
Two color pyrometers are useful for measuring temperature in very precise locations with a fast response. The effect of the fiber core on the measurement is a very important parameter, due to its influence in the measurement area and in the temperature range that can be measured.

(MDPI, 2018-02-06) Vázquez García, Carmen; Pérez Prieto, Sandra; López Cardona, Juan Dayron; Tapetado, Alberto; Blanco, Enrique; Moreno López, Jorge; Sánchez Montero, David; Contreras Lallana, Pedro
We report the experimental results on a new infrared fiber-optic pyrometer for very localized and high-speed temperature measurements ranging from 170 to 530 °C using low-noise photodetectors and high-gain transimpedance amplifiers with a single gain mode in the whole temperature range. We also report a shutter based on an optical fiber switch which is optically powered to provide a reference signal in an optical fiber pyrometer measuring from 200 to 550 °C. The tests show the potential of remotely powering via optical means a 300 mW power-hungry optical switch at a distance of 100 m, avoiding any electromagnetic interference close to the measuring point.

(IEEE, 2017-09-04) Vázquez García, Carmen; Tapetado, Alberto; Pinzón, Plinio Jesús; Sánchez Montero, David; López Cardona, Juan Dayron; Contreras Lallana, Pedro; Zubia, Joseba
Temperature is a major magnitude that needs to be measured in many different scenarios such as monitoring the temperature during manufacturing process, in aeronautical engine performance, or in all electrical aircraft batteries performance among others. Fiber optic temperature sensors have very interesting properties due to its potential to provide electromagnetic interference immunity, light weight, intrinsically safe nature, and depending on the technology high temperature range and remote operation. In this talk we will review our recent progress on intensity fiber-optic temperature sensing with different technologies and applications.
