A novel self-calibrated interferometer/industry-based (SCIIB) fiber optic sensor is described in this paper. The novel sensing scheme combines the advantages of both fiber interferometry senors and intensity-based sensors. The sensor operates on a single fiber Fabry-Perot interferometric cavity with a white light source. The interference signal of the sensor is coherent-sliced into two channels. Which allow fully real-time compensation for the source power drifting and fiber los variation. Temperature and pressure sensors with various dynamic ranges were designed and fabricated based on the SCIIB technology. Experimental result show that the SCIIB sensor scheme achieves excellent resolution and accuracy with the self- calibration function.
