Took place in 2014, June, 02-06, in Santander (Spain).The design and development of a plastic optical fiber (POF) macrobend temperature sensor is presented. The sensor has a linear response versus temperature at a fixed bend radius, with a sensitivity of 8.2 ∙ 10−4(ºC)−1 〖8.2.10〗^(-4) 〖(°C) 〗^(-1) and a 8% non-linearity full scale error. The sensor system uses the power variation between two discrete wavelengths for auto reference purposes. An analysis for selecting operation wavelengths has been carried out in order to optimize the response of the sensor. The proposed sensor can be used in harsh environment and has a low-cost4application/pdfeng© 2014 Society of Photo Optical Instrumentation EngineersPOF Sensortemperatureintensitybend lossloopself-referenced.conference paperElectrónicaIngeniería IndustrialÓptica10.1117/12.2059297open access19157164Proc.
