Application of Digital Speckle Correction Method to Inverted Camber Detection of Prestressed Foundation Beam
Based on the principle of digital speckle correlation method (DSCM), a distance measuring DSCM system has been developed and realized. With the application of the system, the inverted camber of a pre-stressed beam of beam-slab transfer cadre was traced and analyzed in this paper. Compared with other experimental technique such as dial indicator test method, it shows that DSCM is a powerful optical deformation measurement tool with the required precision and on-site inspection ability.
