摘要：
The authors characterize four U-shaped plastic optical fiber sensors, manufactured with a particularly developed simple mechanical scheme, which are characterized and implemented as refractometry sensors. The enhanced measurement set-up consists of an LED and a photodiode connected to the ends of the fiber, while the signal is detected by a Lock-in amplifier implemented in Matlab. The calibration process led to the evaluation of the sensitivity, accuracy and repeatability by using solutions of sucrose for obtaining refractive indexes in the range of 1.33 - 1.39.
