Abstract
This paper presents a brief overview of research activities in fiber optic sensors at the Applied Physics Division of the Scientific Center CICESE. Started in 1992, the research was directed to develop a new wavelength scanning technique for multiplexing and interrogation of a serial array of interferometric sensors in polarization-maintaining fiber. A further developing of this technique resulted in a new approach for multiplexing and demodulation of Bragg grating-based sensors. A novel algorithm has been developed for digital demodulation of the twin-grating sensor, which provides absolute high resolution measurements in a wide dynamic range. Recent experiments on testing a twin grating fiber optic sensor demonstrate very promising results. A few other developed sensing techniques are also presented in this paper.
