SHM of Unmanned Aerial Vehicles (UAV’s) Using Embedded High Definition Fiber Optic Sensing (HD-FOS)

Embedded fiber sensors as an alternate approach to structural validation of composite structures At the September 2015 International Workshop on Structural Health Monitoring (IWSHM) held at Stanford University, a paper was presented [1] detailing how distributed fiber optic sensing using Rayleigh backscatter could be used as a practical and effective means to validate the structural integrity of a fleet of High Altitude Long Endurance (HALE)…Read More

Luna Innovations high definition fiber optic sensing is the ideal solution to measure strain and temperature on printed circuit board assemblies (PCBA’s)

Market trends driving electronics manufacturers to include FE analysis and strain testing of PCBA’s As machinery becomes increasingly sophisticated the reliance on electronic controls is growing.  The building block of any electronic control system is the PCBA and these can be found everywhere; in home appliances, automobiles, wind turbines, data centers and personal computers. Although taken for granted, the orderly functioning of our every day…Read More

HD-FOS helping to integrate composites into the design and validation frame work for the aerospace industry

  Luna Innovations will be speaking at the September 22nd JEC Forums (Boston) conference, titled “Validating Composite Design using High Definition Fiber Optic Sensing (HD-FOS)”.  The presentation specifically targets how HD-FOS can help to advance the integration of composites into the design and validation framework of aircraft production.  Composites now make up 50% of the material used in the latest generation of commercial aircraft. With…Read More

Embedded fiber optic sensing of composite-overwrapped pressure vessels

  Luna Innovations will be presenting a paper at the upcoming CAMX show titled “In-Situ SHM of Composite-Overwrapped Pressure Vessels”.  The paper is a collaboration with Structural Composites Industries (SCI), a leading commercial and military supplier of composite overwrapped pressure vessels (COPV), and demonstrates a novel approach to structural health monitoring (SHM) of air flasks using embedded high definition fiber optic sensing (HD-FOS) technology. Luna’s…Read More

Luna Innovations ODiSI platform with HD-FOS technology for temperature enables automotive engineers to expand the limits of design

When components are designed for aerospace, automotive or other general industrial applications, design factors are used to account for unknowns in the application or limitations in design validation. These design factors can come at a price in the form of excess material and cost.  In cases where knowledge of the application is insufficient to determine the correct design factor, premature component failure may result.  It…Read More

Testing for Residual Strains in 3D Printed Components using High Definition Distributed Fiber Optic Sensing (HD-FOS)

  In the May 2015 issue of the Harvard Business Review, Richard D’Aveni states that additive manufacturing is on the brink of completely transforming the design and production ecosystems for manufacturers of tangible goods.   https://hbr.org/2015/05/the-3-d-printing-revolution  Additive manufacturing frees both designers and manufacturers from many of the constraints of the normal product design, prototyping and industrialization process.  The cost and lead time for tooling can be…Read More

Design Validation of Wing Morphing Using Fiber Optic Distributed Sensing

Josiah Fee In response to government initiatives such as the FAA’s Continuous Lower Energy Emissions and Noise (CLEEN) program, aircraft manufactures are working on new technologies to increase efficiency and reduce noise.  The design of a morphing wing leading edge is one method that can be used to accomplish these goals. Traditionally, slats are used to increase the angle of attack of a wing for…Read More

Detecting Tunnel Excavation Sites Using Rayleigh Scatter Sensing

Jordan Stringfellow Mechanical Engineer llegal underground cross-border tunnels have been a challenging problem over the last few decades, especially in areas such as the Gaza strip and US-Mexico border. Increased smuggling of drugs, weapons, and people, has made it more important than ever to find an advanced solution to detect and locate these tunnels. Tunnels can range in sophistication, diameter, and depth, depending on their…Read More

Detecting Cracks In Steel Bridges Using Fiber Sensors

Jordan Stringfellow Mechanical Engineer Lightwave Division According to the American Society of Civil Engineers (ASCE) in its 2013 Report Card for America’s Infrastructure, one in four bridges in the Unites States are “either structurally deficient or functionally obsolete”. It is approximated that $3.6 trillion is needed to improve the United States’ current infrastructure grade of D+ to an average grade of B. Infrastructure management teams…Read More
