Multiplexed Bragg grating laser sensors for civil engineering
A portable, rugged, and compact 4-channel Bragg grating fiber laser sensor demodulation system was developed for interrogating an array of 20 - intracore Bragg grating sensors that the authors embedded within several of the concrete girders used to support the deck of a new two span road in Calgary. Another unique feature of this bridge is that two types of Carbon fiber based composite prestressing tendons are being tested in a number of the concrete girders. The authors have instrumented fiber of the nearly equal 60 ft long concrete girders with fiber optic Bragg grating strain and temperature sensors in order to monitor the loads on these girders and their response during the construction of the bridge and subsequently over an extended period of time.
