Abstract

Single crystal sapphire fiber sensors have been embedded in an aluminum alloy component fabricated via the ultrasonic additive manufacturing (UAM) process. To demonstrate feasibility of distributed temperature measurements with the embedded fibers, a recently developed Raman scattering based sensing scheme was utilized to obtain the distributed Stokes and anti-Stokes intensity measurements as a function of distance along the fiber upon selectively heating the fiber embedded components to various temperatures.
