Self-Driving Vehicles: Evaluating Damage and Wear with Smart Parts

Fiber optic sensors have unique characteristics such as their low profile, flexibility and resistance to chemicals and corrosion that make them uniquely suited for long-term and embedded applications. This creates an opportunity for a design to incorporate “smart parts” that can easily communicate their health to an inspector. Instead of relying on visual confirmation or disassembly of the vehicle to check on hard-to-get-to structural elements,…Read More

Creating a Self-Measuring Smart Structure with a Fully Distributed Strain Rosette

With the integration of new materials into applications and structures, developing strain profiles to characterize material behavior, conduct structural health monitoring and enable in-situ non-destructive testing requires a different measurement solution. Due to their small size, flexibility and low weight, High-Definition Fiber Optic Sensors (HD-FOS) have been frequently utilized for highly spatially-resolved strain measurements on a wide variety of materials and complex part geometries. Luna…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

Protection Methods for Improved Durability of Fiber Optic Sensors

Accidental damage to ODiSI fiber optic strain sensors can occur in a variety of ways. As an example, in the instrumentation of large test articles, such as an aircraft wing, it is easy to overlook the low sensor profile. It then becomes possible for the sensor to be unintentionally stepped on or for tools to be dropped on it, resulting in a broken sensor. In other instances,…Read More

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

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
