Measuring Uniformity of Cure Temperatures Using High-Definition Fiber Optic Sensing

The use of composite materials is ever increasing due to their high strength to weight ratios, manipulative properties, multifunctional capabilities and corrosion resistance. To fabricate high-quality composite components with acceptable thermal properties, elevated temperature cure cycles are typically required. Maintaining uniform heat distribution throughout the curing composite can be critical to the performance of the resulting part. Thermocouples are typically used to both monitor and…Read More

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

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

Enhancing Weapons Readiness: Fatigue Cracking Analysis for Gun Barrels

Every time a gun is fired, enormous gas pressures are generated inside the barrel to propel a projectile toward its intended target. For perspective, typical pressures can exceed 50,000 pounds of force per square inch:  over three times the water pressure at the deepest ocean depths. The resulting stresses in the barrel’s wall impart fatigue damage each time a round is fired, initiating cracks that…Read More
