Optical Fiber Grating Sensing for Infrastructure Monitoring in China

Abstract

Fiber grating sensor technology has attracted substantial industrial interests in the last decade. They have increased in acceptance and widespread use for structural health sensing and condition monitoring applications in civil engineering, aerospace, marine, oil & gas, and railways. Most civil structures built by the Chinese Government in the past five years are instrumented with FBG sensing networks. FBG sensors are unique compared with other types of optical sensors and have proven to be durable and reliable, and offer tremendous benefits to the building, petrochemical and railway industries. As more FBG sensors are employed in these industries, more intimate information will be gained to realize the full potential of the FBG sensor technology to realize truly intelligent monitor systems for the various industries.
