Abstract

The rapid growth and implementation of fiber optic sensor devices have evolved to the stage of demonstration and in-situ applications, whereas normally pressure and temperature parameters are measured. New photonic space opto- electronic systems could sense in a distributed way impact, damage assessment and pressure variations in structural integrity testing of spacecraft and platforms. The system consists of several loops (up to 8 per control unit) of fiber optic sensors or cables buried or implemented in smart structures or complex materials in wings or structures. Signal processing has been performed by FDM/TDM techniques to interrogate and to demultiplex unambiguously the fiber optic sensors. The control units could be placed locally or centrally in a network configuration to interrogate up to 256 loops or single sensors.
