Abstract
This paper presents the evaluation of a removal method to cancel the thermal convection effect that is generated in vertically positioned metal plates loaded by thermal waves when a lock-in temporal speckle pattern interferometry technique is used to detect hidden flaws. Additionally, the resolution of this technique to detect two nearby flaws is also analyzed.
