Abstract

Holography has been used in the electric utility industry in practical tests for deformation of pipes subjected to repair procedures. In research studies, the use of holography for measurement and NDT (nondestructive testing) has been explored for pipes. The expected interferograms have been simulated with a mathematical model which embodies elastic deformation as well as rigid body motion. Experimental verification of the model shows that it may be used for software compensation of rigid body motion, and for measurement of bending, torsion, pressure, and thermal expansion.
