Paper Abstract

Self-calibrated interferometric/intensity-based (SCIIB) fiber sensors are describe in this paper. The sensor operates on the absolute detection of signals form a Fabry- Perot interferometric cavity. The incorporation of coherence-sliced self-calibration allows compensation for all unwanted factors, such as source power variations and fiber loss changes. Pressure sensors with various dynamic ranges were designed and fabricated based on the SCIIB scheme. Experimental results indicate that the novel sensor scheme offers excellent resolution and accuracy with absolute measurement and self-calibration function.
