Title:
NON-DESTRUCTIVE INSPECTION METHOD FOR MECHANICAL BEHAVIOUR OF ARTICLE
Document Type and Number:
WIPO Patent Application WO/1995/010023
Kind Code:
A1
Abstract:
This invention contemplates to provide a method of executing a non-destructive inspection by a speckle method even when an object of inspection has rigid-body motion. The present invention uses a first camera (15) for measuring the total displacement quantity of an object and a second camera (21) for measuring the displacement quantity of the object due to a rigid-body motion by monitoring a reference point in the object. The displacement quantity due to rigid motion is subtracted from the total displacement quantity to obtain a displacement quantity reflecting only the displacement quantity resulting from deformation as a speckle pattern. The method of the present invention can obtain only the displacement quantity resulting from deformation by offsetting the displacement quantity of the object due to a rigid-body motion.
