Paper Abstract

Fiberoptic Raman backscatter based distributed temperature measurement systems have been available for several years. Recent efforts at Boeing have focused on developing methods to apply this equipment to monitoring the temperature of composite parts during manufacture, laboratory testing, and on-board application for health monitoring. A number of these applications involve embedding the temperature-sensing fiber directly into or onto composite parts. Several examples are given and lessons learned are discussed, including effects of microbending losses and how they are being addressed.
