- Abstract:
- We apply optical coherence tomography (OCT) and a modification thereof, namely polarisationsensitive OCT (PS-OCT), to a variety of problems posed in metrology for material analysis and diagnostics. Among these are imaging of glass-fibre enforced epoxy resin compounds and the detection of dry spots. Furthermore, PS-OCT measurements have been used to measure the birefringence and the orientation of the fast optical axis within test structures: mapping of strain fields of samples under uni-axial and non-uniform external stress and the detection of flow patterns in injection-moulded plastic parts could be successfully demonstrated.
