Abstract

In this study, U-shaped fiber optic sensor tips sensitive to refractive index (RI) change were produced, and its performance analyses were carried out. Three sensor tips were used to measure ethanol/methanol-water mixtures in concentrations from 0% to 16.66%. The ethanol sensor tip was able to detect the RI change of 4×10-4 RIU. Its maximum sensitivity is 7.71 mV/RIU, and its linearity is 0.9985. The methanol sensor tip was able to detect the RI change of 1×10-4 RIU. Its maximum sensitivity is 28.49 mV/RIU, and its linearity is 0.9969. Each sensor tips determine the change of 1.41% concentration in the mixtures. Moreover, the results show that it can provide high precision in the measurement of ethanol/methanol-water mixtures and achieve satisfying stability and repeatability.

Özet

Bu çalışmada kırılma indisi (RI) değişimine duyarlı U-Şeklindeki fiber optik sensör uçları üretilmiş ve performans analizleri yapılmıştır. %0 ile %16,66 arasındaki konsantrasyonlarda etanol/metanol-su karışımlarını ölçmek için üç sensör ucu kullanılmıştır. Etanol sensör ucu, 4×10-4 RIU’luk kırılma indisindeki değişimi tespit etmiştir. Etanol sensör ucunun maksimum hassasiyeti 7,71 mV/RIU ve doğrusallığı 0,9985’tir. Metanol sensör ucu ise 1×10-4 RIU’luk kırılma indisindeki değişimi tespit etmiştir. Bu ucun maksimum hassasiyeti 28,49 mV/RIU ve doğrusallığı 0,9969’dur. Her bir sensör ucu, karışımlardaki %1,41 konsantrasyondaki değişikliği belirlemiştir. Ayrıca sonuçlar, sensör uçlarının sadece etanol/metanol-su karışımlarının ölçümünde yüksek kesinlik sağlamakla kalmayıp aynı zamanda tatmin edici kararlılık ve tekrarlanabilirlik sağladığını da göstermektedir.
