The Leading Edge – Observing Crack Strain with the FAA

Luna engineers were invited to the Federal Aviation Administration (FAA) William J. Hughes Technical Center in Atlantic City to participate in testing an aircraft fuselage panel. Several issues related to the structural integrity of fuselage applications are being examined using the Full-Scale Aircraft Structural Test Evaluation and Research Lab (FASTER), including the fatigue and damage tolerance characteristics of current and emerging metallic and composite designs, performance…Read More

13 HYPERION Optical Sensing Interrogators Monitor Structural Health of the World’s Longest Sea-Crossing Bridge

The Hong Kong-Zhuhai-Macau Bridge (HZMB) is designed to have a lifespan 120 years. The mega-structure, which opened October 24, is built to withstand a magnitude 8 earthquake, a super typhoon and strikes by super-sized cargo vessels.  However, the Pearl River Delta operational environment is one of the world’s most densely urbanized regions. Degradation and aging from the environment and operation, along with natural and man-made…Read More

Developing Advanced Sensor Instrumentation for Next Generation Nuclear Plants

New nuclear power generation is an important non-fossil fuel option to meet future global electricity demands. To ensure public safety and maintain energy security, the new reactors must be significantly safer and more efficient than previous designs. The Gen-IV design initiative is driving the development of the next generation nuclear plants with designs such as the Molten Salt Reactor, Sodium-cooled fast reactor, Lead-cooled fast reactor,…Read More

What is HD-FOS and How Does it Deliver New Testing Insight?

As the automotive industry continues to develop new lighter weight material systems and move to electrification, new design challenges are created that will require new advanced methods for test, measurement and validation. Fiber optic sensors can reduce time to first measurement and go where strain gages and temperature sensors cannot – in tight bends, on small details and even embedded inside composite materials. In addition,…Read More

Luna Labs at Defense TechConnect Fall Summit & Expo

This year at the annual the Defense TechConnect (DTC) Fall Summit, Luna will be exhibiting the capabilities of Luna Labs (the Technology Development Division of Luna Innovations). At our booth, DTC attendees have the opportunity to meet with Luna’s team and understand how Luna Labs can work with their organization to create technologies which save time, save money, and save lives. Luna can be found…Read More

Measuring Uniformity of Cure Temperatures Using High-Definition Fiber Optic Sensing

The use of composite materials is ever increasing due to their high strength to weight ratios, manipulative properties, multifunctional capabilities and corrosion resistance. To fabricate high-quality composite components with acceptable thermal properties, elevated temperature cure cycles are typically required. Maintaining uniform heat distribution throughout the curing composite can be critical to the performance of the resulting part. Thermocouples are typically used to both monitor and…Read More

Optical Reflectometers – How Do They Compare?

Measuring the return loss along a fiber optic network, or within a photonic integrated circuit, is a common and very important technique when characterizing a network’s or device’s ability to efficiently propagate optical signals. Reflectometry is a general method of measuring this return loss and consists of launching a probe signal into the device or network, measuring the reflected light and calculating the ratio between…Read More
