Abstract

Research on optical interferometry has been applied to examine object deformations caused by static & dynamic loading. This method makes use of coherent beam phase alteration recorded in image recording system. In general, the system consists of three systems i.e. optical system, image recording system, and image processing system. Optical system (optical set-up) will determine the deformation shape, image recording system which function as recording before (initial condition) and after deformation. Image processing system will determine the deformation. By means of static & dynamic tests on aluminum plate, it is shown that this system can lends itself to determine object deformation and has light beam order of accuracy. Therefore, deformation distribution can be quantitatively interpreted by analyzing the fringe pattern.
