This paper presents multi-functional OCT, i.e. Dynamic Optical Coherence Stressgraphy (D-OCSE), Dynamic Optical Coherence Straingraphy (D-OCSA) and Optical Coherence Thermoghraphy (OCTH), which can diagnose mechanical properties of polymer matrix materials tomographically. In this study, the proposed system was constructed, and the validation experiment was carried out. Consequently, micro-tomographic distribution of stress & strain rate as well as temperature can be measured simultaneously and non-destructively. It was, therefore, concluded that D-OCSE & D-OCSA and OCTH could provide micro-mechanical information experimentally like FEM analysis, which is a fracture diagnosing tool of polymer matrix materials.
