D-Shaped POF Sensors for Refractive Index Sensing—The Importance of Surface Roughness

D-Shaped POF Sensors for Refractive Index Sensing—The Importance of Surface Roughness

In this study the influence of the surface roughness on the transmission capacities of D-shaped plastic optical fibers (POFs) and sensors performance was investigated. Five D-shaped POF sensors were produced and characterized for refractive index sensing between 1.33 and 1.41. The sensors were chara...
