Abstract

Embedded fiber-optic sensors offer an attractive method for real-time in-situ characterization of composite materials. The present work is directed toward the development of an appropriate optical waveguide and sensing technique for high temperature ceramic applications. The waveguide consists of a sapphire optical fiber core and polycrystalline alumina cladding. The sensing technique is based on spatial intensity modulation induced within multimode optical fibers. This paper presents a brief description of the optical waveguide fabrication, a theoretical model for spatial intensity modulation (SIM) and experimental verification of SIM in sapphire fibers.
