Fiber Optic Shape Sensors


Sense changes in shape in real time without affecting performance and without the need for structural modifications

NASA’s Dryden Flight Research Center has developed a shape-sensing technology that offers high resolution (0.5-inch) at a 60-Hz refresh rate. The technology is contained in a small, lightweight package the size of shoebox that uses fiber Bragg grating (FBG) sensors and ultra-efficient, real-time algorithms. It is capable of interrogating and processing information for 1,000 sensors at a rate of 60 times per second. This innovation is available for commercial licensing and has applications in many areas including automotive, aeronautics, wind energy, medicine and structural health monitoring.

Additional Benefits

  • Multiple engineering measurements (e.g., strain, temperature, structural shape)
  • Non-intrusive design that does not affect structure’s performance
  • Off-the-shelf-components assembly and customizable software code from NASA
  • Robust design resistant to any (or all) electromagnetic/radio frequency interference and radiation

Why It’s Better
With significant advantages over current sensing technologies, this technology provides the capability to acquire a large number of accurate surface strain, temperature and displacement measurements in real time for large structures that are undergoing a wide range of displacements during operation. Data acquisition is possible with a minimal weight penalty. Furthermore, this is the only technology available that can provide out-of-plane structural deflection, local strain and temperature measurements in real time.
