|Title:||Simultaneous Measurement Of Refractive Index And Temperature Based On Multimode Interference Inside A Fiber Loop Mirror|
|Abstract:||A fiber optic sensor for simultaneous measurement of refractive index and temperature is presented. The sensing probe is achieved by introducing multimode interference inside a high birefringence fiber loop mirror resulting in a configuration capable of refractive index and temperature discrimination. The multimode interference peak is sensitive to the surrounding refractive index (90 nm/RIU) and slightly responsive to the temperature (0.005 nm°C). On the other hand, the birrefringent fiber loop mirror is highly sensitive to temperature (2.39 nm°C) and has no response to refractive index. Therefore, a temperature independent refractive index measurement can be made with a resolution of ±2.5x10-5. © 2012 SPIE.|
