Abstract：

Fourier-domain　(or　spectral-domain)　Infrared　Optical　Coherence　Tomography　(FDOCT)　can　penetrate　into　the　scattering　material　noncontactly　and　therefore　it　can　be　used　to　characterize　and　image　the　inner　structure　of　material　in　a　non-invasive　manner.　In　the　paper,　glass-fibre　reinforced　polymer　(GFRP)　materials　were　quantitatively　characterized　by　using　home-made　FDOCT　system.　In　the　developed　FDOCT　system,　a　50W　Tungsten　halogen　lamp　and　a　highperformance　spectrometer　are,　respectively,　employed　as　the　light　source　and　the　detector.　The　broadband　of　the　spectrometer　and　thermal　light　source　results　in　the　FDOCT　system　with　high　robust　performance　and　an　excellent　depth　resolution　of　0.7　um.　From　the　experimental　results,　the　developed　FDOCT　system　could　be　recommended　in　nondestructive　testing　or　health　monitoring　of　GFRP　materials.
