New Markets for Fiber Optic Strain Sensing

Posted April 14, 2016 12:00 AM by Engineering360 eNewsletter

Strain measurement is critical to designing structures that will be experiencing high stresses.Fiber optic sensing (FOS) systems have a number of advantages over traditional resistive strain gauges. The main advantage of FOS is that a single optical fiber can collect data from thousands of sensors, providing a continuous strain profile. It was used by NASA to plot the real-time strain variation along an UAV wing during actual flights, for example. Another application is validating the design of wind turbine blades under actual operating conditions. Although FOS technology is not being widely used right now, this article predicts it will find new markets as the cost of the system is reduced over the next five years.
