Introduction

At Luna, we have developed a

lightweight (nearly weightless), flexible,

inexpensive, easy to install and ultra-

high definition sensor technology.

We are addressing key challenges

encountered in the automotive,

aerospace and energy industries

presented by the evolution towards

more fuel efficient, lighter weight,

higher strength and greener designs.

Today we will talk about:

• High-definition strain mapping

ODiSI Strain Measurement System

Extraordinary Spatial

Resolution A strain measurement along every millimeter of

fiber is perfect for detecting high strain gradients

and studies of crack propagation

Low Profile Sensor For

Embedded ApplicationsA fiber sensor can be unobtrusively embedded

within composite structures

Environmentally Robust SensorA fiber sensor is corrosion proof, immune to

EMI/EMC and introduces no source of ignition

Mapping of Strain ContoursThe fiber is flexible and can be routed in

serpentine pattern, providing a full field view of

strain

ODiSI Strain Measurement System

Motivation: Why Optical Fiber?

• Small (150 micron diameter)

• Lightweight

• Flexible

• Strong

• Immune to RF/EMI

• Measure many points with

one connection

The Interrogator

At right is Luna’s ODiSI, a single channel system using fiber

sensors to measure distributed strain.

The Sensor

Sensors are lightweight, minimally invasive and can be embedded

within structures. The fiber is EMI immune and introduces has no

electrical signal (no source of ignition).

The Switch

An optical switch can be used to serially interrogate multiple

sensors. Luna offers both an (8) and (36) channel switch that can

convert a single channel interrogator into a multi channel system.

The Equipment

The 3D Visualization

Our system provides much more data about the customer’s test.

Our data visualization and CAD integration tool allows engineers

to quickly interpret this data and to zoom in on the critical areas.

• Reduced instrumentation time

• Instrumented in places inaccessible with traditional strain gages

• Gage location, gage length and spatial resolution completely configurable through software

• Export data for analysis or for use with 3D visualization tool

• Using software, locate peak along fiber sensor and then display strain vs time at select points

9

Component Lightweighting – Leaf Spring

A high definition distributed strain sensor allows for strain gradient measurement across the whole leaf spring

• Fiber is bonded across the full surface of the leaf spring with loading applied to top

• Three strain gages are positioned along the leaf spring

• Loading is incremented from 0 to 180 lbs. A comparison of the fiber and strain gage is clear in the graph

Lightweight designs joining dissimilar materials will require a greater use of adhesives

• The high density distributed measurement of fiber is ideal for validating the integrity of adhesive joints

• The fiber can be routed across or embedded within the joint

• The test data can be used to validate finite element modeling of the joint and test the joint’s integrity under variable conditions

• Embedding fiber yields data on stress and strain not available any other way

• Ideal for determining residual stress and strain resulting from manufacturing process

• Fibers embedded permanently in components can be used for structural health monitoring

In many composite applications the fiber sensor can be embedded within structures during the fabrication process

Embedded Sensor in Composite Pressure Vessel

• Flask ends stiffer due to thicker metal liner causing the

strain to be lower near the ends

• Structure variation visible in strain data and is consistent at

each pressure level

Summary: Luna Advantages

Our breakthrough HD-FOS solution will accelerate

your lightweighting programs while mitigating risk

• Provides high definition distributed strain map

• 1000 plus sensing points per meter of fiber provides a complete

picture of strain gradients and strain peaks

• 3D visualization tool offers quick interpretation of data

• Low profile sensor can instrument in places where strain gages

can’t go

• Mount fiber on edges, across welds and inside adhesive joints

• Embed within composite structures

• More cost-effective

• A single fiber sensor can fully cover a large test article

• No individual wiring or gage calibration

• Cost savings increase as test article size increases
