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

Fiber Sensing Helps Validate Viability of the PRSEUS Concept in General Aviation

Josiah Fee Mechanical Engineer Lightwave Division Composites are a vital part of today’s and tomorrow’s aircraft innovation. With their high strength-to-weight ratio compared with metals, composites have opened up the possibilities for a number of novel aircraft structural designs. One such design is the Pultruded Rod Stitched Efficient Unitized Structure (PRSEUS) concept. This involves using a stitched skin and stringer-and-frame carbon fiber preform design for…Read More

ODiSI-B Software Update

  Great news for new and existing ODiSI-B users! Toward the end of 2014, Luna released a major software update for the revolutionary ODiSI-B strain and temperature measurement platform. The ODiSI (Optical Distributed Sensor Interrogator) uses low cost optical fiber to provide high speed, fully distributed strain and temperature measurements. It saves time and costs while adding a new dimension to sensing measurements with its…Read More

Getting More from Fatigue Testing

John J. KutzApplications EngineeringLightwave Division Fiber optic sensors have a great combination of simple installation, repeatability and fatigue endurance that make them well suited for use in fatigue testing. Characterizing fatigue behavior of parts or structures is important in applications where parts are subjected to cyclic loading. such as fan or turbine blades commonly used in aerospace, automotive, power generation and the HVAC industries. Getting…Read More

What can you see with High Spatial Resolution RL?

Aida Rahim, PhDField Applications EngineerLightwave Division Our previous blog post on return loss (RL) gave an overview of some examples of events along the optical network that cause high RL, and their effects. To recap, in technical terms, RL is the ratio of the light reflected back from a device under test, Pout, to the light launched into that device, Pin, usually expressed as a…Read More
