Developing Advanced Sensor Instrumentation for Next Generation Nuclear Plants

New nuclear power generation is an important non-fossil fuel option to meet future global electricity demands. To ensure public safety and maintain energy security, the new reactors must be significantly safer and more efficient than previous designs. The Gen-IV design initiative is driving the development of the next generation nuclear plants with designs such as the Molten Salt Reactor, Sodium-cooled fast reactor, Lead-cooled fast reactor,…Read More

What is HD-FOS and How Does it Deliver New Testing Insight?

As the automotive industry continues to develop new lighter weight material systems and move to electrification, new design challenges are created that will require new advanced methods for test, measurement and validation. Fiber optic sensors can reduce time to first measurement and go where strain gages and temperature sensors cannot – in tight bends, on small details and even embedded inside composite materials. In addition,…Read More

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
