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

Develop More Reliable Batteries with High-Definition Fiber Optic Sensing

Lithium-ion batteries, with high energy density and long life compared to other rechargeable chemistries, are widely used today in devices ranging from cell phones to laptops to vehicles. One drawback of these batteries, however, is that an internal fault can initiate heating and very quickly trigger a positive feedback loop that can result in a dangerous thermal runaway event. High-Definition Fiber Optic Sensing (HD-FOS), provides…Read More

Improve Process Temperature Monitoring in Thermoplastic Welding

Embed Fiber Optic Sensors for In-situ Temperature Measurements at the Weld Zone An important innovation in the ongoing adoption of lightweight materials is the use of induction welding to join composite materials based on a thermoplastic polymer. With this process, an induction coil creates eddy currents within two composite parts. The process heats the polymer to the point of melting. The two parts are pressed…Read More

Luna to exhibit and present at GALM in Detroit, MI

Next week, Luna is excited to participate in GALM Detroit — the world’s leading automotive lightweight materials conference.  With a focus on implementing lightweighting innovations and optimizing multi-material architectures for EV’s, autonomous vehicles, and next-gen ICEV’s, this event is ideal for Luna to showcase our ODiSI system and its ability to characterize strain on/in new materials and complex structures.   We encourage you to stop by…Read More

IEEE GlobalSpec to host webinar featuring the Optical Backscatter Reflectometer (OBR)

High-resolution optical backscatter reflectometry (OBR) has become a valuable tool in the design, test and diagnostics of fiber components, photonic integrated circuits (PICs) and short fiber networks. In much the same way that standard OTDRs identify and locate issues and sources of loss in long-range fiber optic systems, high-resolution OBRs can locate and identify issues and defects with sub-millimeter resolution and since they don’t suffer…Read More

ODiSI Fiber Optic Sensing Featured in CompositesWorld

The June 2018 issue of CompositesWorld highlights Luna’s ODiSI measurement system and its value in the design and testing of composite materials and components.  The design and validation of composite components and systems is significantly more complex than for traditional materials, and the article describes how high-definition fiber optic sensing (HD-FOS) is uniquely suited for composite test and measurement.  Specifically, HD-FOS can be used to:…Read More

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
