| Popis: | A new scheme is proposed for simultaneous strain and temperature measurement with a single-fiber Bragg grating. The grating sensor was written on the splice joint between two fibers and has two resonance peaks because of the different refractive index between the two fibers. By bonding one section of the grating onto the substrate of large thermal expansion coefficient, the two resonance peaks exhibit different strain and temperature response and can thus be used for strain/temperature discrimination. © 2002 Wiley Periodicals, Inc.
