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.
