Abstract : A novel sensor array made of twined steel2cable2like multimode optical fibers is
presented. It can be used to detect many state parameters such as load and st rain of intelligent material and st ructure. OTDR technology is applied to process real2time parallel and dist ributed sensing signals. The experiment result s demonst rate that this system can be used to detect and estimate st ructure and state online , which is of practical value.
Key words : fiber optic sensor ; intelligent material and st ructure ; OTDR
