Paper Abstract

The kinematics of deformation of the object to be studied is combined with the formation of this holographic image by using the tensor analysis as a mathematical means. A relational expression for the surface and interior strain of a diffused object versus its rotation measurement is derived from the optical-path difference. With the ZFC method of a single hologram, a herculite container, as an experiment, is measured. The experimental results are in agreement with a strain gage.
