The ability to accurately measure real-world physical phenomena--such as strain, temperature and vibration--is critical to engineers developing and delivering new technologies and innovations. While traditional data acquisition systems, based on discrete electrical sensors such as thermocouples and strain gages, have long been the go-to tool for these measurements, they have real limitations in addressing the evolving needs posed by modern engineering. New developments in fiber optic sensing provide unique measurement solutions that can provide new levels of valuable data and visibility not available with traditional approaches.
This webinar explains how fiber optic sensing technology has evolved to solve many of the measurement challenges faced by today's engineers and scientists. By providing highly distributed measurements that can be easily made in locations and conditions not compatible with traditional electrical sensors, fiber optic sensors can provide new levels of test data and real-world insight.
Two fiber optic sensing technologies - Fiber Bragg Grating (FBG) and Rayleigh Backscatter - are examined. FBG systems provide high-speed dynamic measurements and the ability to economically provide distributed measurements over very long distances for characterizing or monitoring large areas or structures. Fiber optic sensing based on Rayleigh backscatter delivers continuous measurement profiles with sub-millimeter spatial resolution along a very small and lightweight optical fiber. A live demonstration of a high-definition sensing system based on Rayleigh Backscatter will demonstrate how a test component can be quickly instrumented and analyzed using thousands of strain or temperature measurement points with spatial resolution as low as 0.65 mm.
Examples of how fiber optic sensors solve some key measurement challenges, such as characterizing composite material processes and designs, thermal analysis of batteries and advanced structural health monitoring, will also be offered.
