Back to Basics – Measuring Return Loss

The following is a re-post of a popular past blog post that explains the basics of return loss, why it’s an important measurement, and technologies for measuring return loss. Fiber optic networks span a wide range of lengths. Intercity and transoceanic fiber optic telecommunications networks span thousands of kilometers. In aircrafts and ships, telecommunications systems have link lengths up to 500m. Data center networks have…Read More

HD-FOS in Action this Week at Space Tech Expo

This week at Space Tech Expo in Pasadena, CA, we are showcasing our industry leading ODiSI 6100 measurement sensor for high-definition fiber optic sensing (HD-FOS).  We are highlighting the unique capabilities of the ODiSI 6100 by demonstrating the real-time acquisition of strain across the entire surface of a carbon fiber composite sample.  The composite sample was instrumented with a Luna HD strain sensor, a polyimide…Read More

We invite you to join us in Germany next week at the Materials in Car Body Engineering event.  One of our sales representatives, Andreas Stern, will be presenting at this conference.  He will be discussing how our High-Definition Fiber Optic Sensing (HD-FOS) technology is solving some of the most challenging verification tasks in the design and manufacturing of components and systems using advanced materials, such…Read More

Using HD-FOS for Safer, More Stable Excavations and Tunnels

Tunnels and other underground excavations typically require some form of ground support or reinforcement to increase the stability of the excavation and improve safety. This support system often takes the form of a combination of support components, such as rock bolts, tendons, umbrella arches and forepoles. Monitoring these ground support components could potentially provide valuable information in assessing the performance of the support system, as…Read More

Fiber Optic Sensing for Very High Temperatures

Fiber optic sensing continues to grow as a valuable temperature measurement tool, thanks to the fiber’s small diameter, small mass and robust operation in harsh environments.  The nuclear industry, for example, has shown interest in fiber optic sensors for very high temperature applications, such as monitoring fuel performance during irradiation or even embedding fiber in commercial reactor components. One option to further extend the temperature…Read More

Embedded Sensors Can Detect Damage in Composites

Combining very high strength with light weight, composite materials are finding their way into more and more structural and cosmetic parts within the aerospace and automotive industries. As composite use grows throughout these industries, efficient and effective methods of non-visual damage detection are needed. To meet this need, Luna has demonstrated that high spatial resolution (0.65 mm) fiber optic strain sensors incorporated into carbon fiber…Read More

Designing Safer Inflatable Space Habitats

An important technology for the future of long term space missions is the use of expandable, inflatable space habitats.  Inflatable habitats are key to reducing the weight of space structures, and are not constrained by the size of the launch vehicle.  In order to ensure the reliability of these structures, Luna is working with NASA and the Embry-Riddle Aeronautical University to research and develop a…Read More

New Component Analyzer for Silicon Photonics and PICs

At the OFC 2018 in San Diego recently, we unveiled the newest member of Luna’s family of high-performance test equipment for the lightwave industry.  The LCA 500 Lightwave Component Analyzer combines industry-leading resolution and sensitivity with high speed and simplified setup to deliver a component characterization solution that extends beyond the R&D lab and onto the production floor. High Fidelity IL, RL and PDL The…Read More

New Measurement System is Multichannel and Real-Time

We recently introduced the newest generation of our distributed strain and temperature measurement platform which is more compact, expands to multiple input channels, and delivers reliable and robust real-time data. Customers are realizing that the ODiSI 6100 delivers a new level of functionality needed to tackle an even wider range of data acquisition applications in the lab, on the production floor, or in the field….Read More

Verifying the Integrity of Composite Adhesive Joints using the ODiSI

Chicken rivets may not sound like a very technical term.  However, it refers to the mechanical fasteners used extensively in the aerospace industry to guarantee the reliability of adhesive bonds of carbon fiber-reinforced plastic (CFRP) materials.   Because adhesive bonds are not very well understood, current certification requirements need proof that should a critical design load be reached, each adhesively bonded joint will not separate and…Read More
