Paper Abstract

Shearography is an optical and nondestructive technique that has been used for damage detection in layered composite materials. In order to facilitate and speed the process of marking of defects during a shearographic inspection of large structures of composite materials, a multimedia projector has been employed. The phase map of the geometry measured by fringe projection is used to mapping the coordinates of the shearographic image acquired during the inspection process with their respective pairs in the projection image. Animations of the shearographic result can be projected on the real structure during the inspection, facilitating the identification and marking of defects by the inspector. This paper shows the principle and algorithms used for the projection of detected defects.
