27 April 2017 Optical frequency domain reflectometry for aerospace applications
Author Affiliations +
Optical Frequency Domain Reflectometry (OFDR) is the basis of an emerging high-definition distributed fiber optic sensing (HD-FOS) technique that provides an unprecedented combination of resolution and sensitivity. We examine aerospace applications that benefit from HD-FOS, such as for defect detection, FEA model verification, and structural health monitoring. We describe how HD-FOS is used in applications spanning the full design chain, review progress with sensor response calibration and certification, and examine the challenges of data management through the use of event triggering, synchronizing data acquisition with control signals, and integrating the data output with established industry protocols and acquisition systems.
