Tunable Laser Development for In-flight OFDR Structural Health Monitoring Systems

Completed Technology Project

Project Introduction

Tunable Laser Development for In-flight OFDR Structural Health Monitoring Systems

Development of a cost-effective, robust, tunable, miniaturized, ruggedized, and flight tested swept laser for in-flight structural health monitoring, based on the NASA-patented optical frequency domain reflectrometry (OFDR) detection scheme. The objective of this effort is to research and develop a NASA flight certified tunable swept laser system that is comparable to the performance of currently-deployed swept lasers but are lower cost, lighter weight, lower volume, and are flight-ruggedized for vehicle health monitoring applications.
