Fiber optic sensors offer many advantages over conventional sensors,
including; small size, low weight, high strength and durability. Standard silica
optical fibers are limited by the material properties of silica. Temperatures above
700°C and other harsh environments are incompatible with standard optical
fiber sensors. Sapphire fiber sensors offer another option for fiber optic sensing.
Sapphire fibers are limited by the material properties of sapphire, which include
high melting point, extreme hardness and imperviousness to chemical reactions
and radiation. These properties coupled with the advantages of conventional
fiber optic sensing make sapphire optical fiber sensors a good candidate for
sensing requirements in harsh environments. We investigate the potential for
the use of sapphire fibers as sensors. Two sensors are developed based on
widely different techniques. Results from preliminary tests of each are given.
