| Abstract: | An in-situ measurement method of moiré interferometry is investigated in this paper. In the method, deformed specimen grating is replicated during an in-situ measurement.The replicated grating containing the load induced deformation. This deformation can be extracted easily by moiré interferometry. This practical method maintains all the advantages of moité interferometry but it make moiré interferometry extended to other application fields out of optical laboratories. |
