Paper Abstract

A new method for determining the displacement fields and inspecting defects inside a loaded or heated object is described. The method uses the carrier holography patterns based on image reconstruction theory. For nonpenetrating material the measure value of projected pattern of displacement fields is obtained from projection of the entire deformable body which is convenient for collecting precise and reliable projection data. A reconstruction algorithm assumes the convolution and is based on a Radon inversion formula. The procedure is applied to a cylindrical body subjected to a concentrated compression on the top.
