A Liquid-Level Sensing Technique Based on Differential Detection of Correlation Peaks From Broadband Chaos
A highly sensitive liquid-level sensing technique is proposed and experimentally demonstrated. Two narrowband fiber Bragg gratings (FBGs) with high reflectivity are used to filter out the two light signals from the broadband chaos. Two weak FBGs are served respectively as the liquid-level sensors at...
