| Abstract: | Digital speckle correlation method (DSCM) has been widely used in experimental mechanics to obtain the surface deformation. But one of the challenges in practical applications is how to obtain the high accuracy with microscopic deformations. A double-microscopic of digital speckle correlation measurement is described in this paper,which can eliminate the rigid displacement and improve the accuracy . Thedesign concept for the optical system, for which double microscope and double CCD is combined to measure microdisplacement is described in our experiment. 4 microscopes were used to testify that the design was rational. |
