Combined　time-　and　wavelength-division-multiplexing　demodulation　technique　of　fiber　Bragg　grating　(FBG)　sensor　arrays　using　a　tunable　pulsed　laser　is　proposed　and　demonstrated.　A　tunable　fiber　laser　based　on　a　matched　FBG　is　applied.　The　wavelengths　of　the　sensing　FBGs　are　obtained　by　detecting　the　maximum　voltages　with　a　photodiode　that　avoids　the　complex　demodulation　process.　The　advantages　of　this　scheme　are　simple　structure,　high　signal-to-noise　ratio,　and　the　sensing　signals　obtained　by　detecting　the　maximum　voltages.
