Nondestructive thermographic detection of internal defects using pixel-pattern based laser excitation and photothermal super resolution reconstruction

no code implementations8 Nov 2022 Julien Lecompagnon, Philipp Daniel Hirsch, Christian Rupprecht, Mathias Ziegler

In this work, we present a novel approach to photothermal super resolution based thermographic resolution of internal defects using two-dimensional pixel pattern-based active photothermal laser heating in conjunction with subsequent numerical reconstruction to achieve a high-resolution reconstruction of internal defect structures.

Thermographic detection of internal defects using 2D photothermal super resolution reconstruction with sequential laser heating

no code implementations1 Mar 2022 Julien Lecompagnon, Samim Ahmadi, Philipp Hirsch, Christian Rupprecht, Mathias Ziegler

Based on a combination of the application of special sampling strategies and a subsequent numerical optimization step in post-processing, thermographic super resolution has already proven to be superior to standard thermographic methods in the detection of one-dimensional defect/inhomogeneity structures.
