Fiber Sensing Helps Validate Viability of the PRSEUS Concept in General Aviation

Josiah Fee Mechanical Engineer Lightwave Division Composites are a vital part of today’s and tomorrow’s aircraft innovation. With their high strength-to-weight ratio compared with metals, composites have opened up the possibilities for a number of novel aircraft structural designs. One such design is the Pultruded Rod Stitched Efficient Unitized Structure (PRSEUS) concept. This involves using a stitched skin and stringer-and-frame carbon fiber preform design for…Read More

ODiSI-B Software Update

  Great news for new and existing ODiSI-B users! Toward the end of 2014, Luna released a major software update for the revolutionary ODiSI-B strain and temperature measurement platform. The ODiSI (Optical Distributed Sensor Interrogator) uses low cost optical fiber to provide high speed, fully distributed strain and temperature measurements. It saves time and costs while adding a new dimension to sensing measurements with its…Read More

Getting More from Fatigue Testing

John J. KutzApplications EngineeringLightwave Division Fiber optic sensors have a great combination of simple installation, repeatability and fatigue endurance that make them well suited for use in fatigue testing. Characterizing fatigue behavior of parts or structures is important in applications where parts are subjected to cyclic loading. such as fan or turbine blades commonly used in aerospace, automotive, power generation and the HVAC industries. Getting…Read More

What can you see with High Spatial Resolution RL?

Aida Rahim, PhDField Applications EngineerLightwave Division Our previous blog post on return loss (RL) gave an overview of some examples of events along the optical network that cause high RL, and their effects. To recap, in technical terms, RL is the ratio of the light reflected back from a device under test, Pout, to the light launched into that device, Pin, usually expressed as a…Read More

What is Return Loss and Why Measure It?

Aida Rahim, PhDField Applications EngineerLightwave Division Optical fiber is the data carrier of choice compared to copper wire. Fiber optic networks have exponentially higher capacity, experience no crosstalk, and can be installed in areas with high electromagnetic interference such as along utility and power lines. Fiber optic networks span multiple length scales. Intercity and transoceanic fiber optic telecommunications networks span thousands of kilometers. In aircrafts…Read More

How Luna’s Fiber Optic Technology Can Help the Racing Industry

Matt Wolfe Chief of StaffLightwave Division Motorsports teams face a variety of challenges every day.  A race car is not just one engineering problem, but a collection of inter-relating engineering problems.  Some of these problems are well understood while others are somewhat a mystery.  In order to learn and understand these unknown problems, race engineers need new tools and instrumentation that will allow them to…Read More

Installing Fiber Strain Sensors – Part II

Eric E. Sanborn, P.E.Director, Engineering and ProductionLightwave Division In the first part of our story on installing fiber strain sensors we covered the basics of applying Luna’s ODiSI sensing fiber to simple parts for measuring strain.  In this second part we will discuss the planning and execution of instrumenting large or complex structures.  The planning stage tends to be a sizable chunk of the total…Read More

Installing Fiber Strain Sensors

Eric E. Sanborn, P.E.Director, Engineering and ProductionLightwave Division In this first part of a two part post we will describe how a fiber optic strain sensor compares physically to a conventional foil gage sensor and how it can be bonded to a simple coupon.  In the second part we will explore instrumenting complex parts and structures.  Luna’s ODiSI sensing solution can replace hundreds or even…Read More
