　　In this study the elastic constants of CFRP plate were measured by an optical full-field measurement technique and an inverse procedure.At first a mirror-like reflective coating was prepared on the surface of a rectangular CFRP plate.The images of a reference grid pattern reflected by the tested plate before and after loading were captured by a CCD camera.
