What if you Could Monitor your Additive Manufacturing Process In Situ?

A recent presentation at the Additive Manufacturing Users Group explored how Luna Innovations and Fabrisonic have been been collaborating on 3D printed “smart structures” to answer this question. A joint team is working with the Defense Logistics Agency to create a smart baseplate capable of measuring strain and temperature during a Powder Bed Fusion (PBF) build. Ultrasonic Additive Manufacturing (UAM), a solid state metal 3D printing technology that…Read More

Luna to Present Papers at the SPIE Defense + Commercial Sensing Conference

Luna Innovations will take part in two paper presentations at the SPIE Defense + Commercial Sensing Conference this week at the Baltimore Convention Center. “Distributed polarization state sensing with optical frequency domain reflectometry” will be presented 11:20-11:40 am Tuesday, April 16. Optical Frequency Domain Reflectometry (OFDR) is notable for its ability to characterize a fiber distributed reflection profile with high spatial resolution and high sensitivity…Read More

SAE Paper Sheds Light on Vehicle Structural Integrity

A team of Luna engineers demonstrated the ability of the ODiSI 6000 Series High Density Fiber Optic Sensing System to make critical design measurements to serve as inputs into computer-aided engineering (CAE) models in normal and off-road conditions. At the SAE World Congress this week in Detroit, Luna will be presenting a technical paper, “Shed Light on Vehicle Structural Integrity.” The presentation is scheduled for 10:30 a.m….Read More

3D Visualization Boosts Strain Data Interpretation and Application

Plotting current strain along a sensor can easily be performed on complex components by Luna’s ODiSI 6000 system. High Definition Fiber Optic Sensing (HD-FOS) provides a wealth of measurements, but these may only have meaning to those who were involved with the test unless preceded with thorough explanation. Members of the design, testing or manufacturing teams need to understand the data, but they may be remote or…Read More

Live, In-Vehicle Strain Monitoring Provides HD Data on Performance of Lightweight Materials

The automotive industry is working towards more sustainable vehicles and lower carbon footprints. One of the ways to achieve this is by decreasing the weight of vehicle components by using composites and other lightweight materials. Compared to commonly used metals, these futuristic materials can be more difficult to model due to more complex failure mechanics and manufacturing processes. High-density strain data can help validate models,…Read More

Measure Latency in Optical Networks with Picosecond Accuracy

In optical networks where action on a message or signal is time critical, latency becomes a critical design element. Latency in communications networks is comprised of the networking and processing of messages, as well as the transmission delay through the physical fiber. Measuring and optimizing this optical transmission delay can be critical in diagnosing latency issues in a data center or maintaining quality control in…Read More

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
