| Abstract: | As a non-contact, high automation and high precision optical deformation measurement method, Digital speckle correlation method (DSCM) is more outstanding than convention deformation measuring technology. After constantly improvement, the theory is becoming increasing sophisticated. As a solid material surface deformation measurement method, DSCM was widely used in solid mechanics experiment, and gets quickly development in the civil engineering deformation measurement. DSCM and its applications in civil engineering are illustrated in this article. |
