“…After image enhancement, faint traces (black) of the horizontal crack can be seen in front of the vertical crack in the lower part of the image. This result supports earlier conclusions [6] that cracks perpendicular to the heating line do not hinder the lateral heat flow enough for the cracks to be easily detected.…”

“…A vertical crack parallel to the line source will stop or hinder the heat flow, and a detectable heat signature should be formed. However, if the crack is perpendicular to the heating line, it will most probably stay undetected [6]. …”

“…LST is an inspection technique in which the specimen can be moved under the line heat source and the monitoring device which are fixed in a stationary position or alternatively the source and the imaging equipment can be moved at a contrast velocity and in a predefined distance over the stationary specimen [137]. The principle behind LST is based on the fact that heat diffusion takes some time to dissipate throughout a material and the temperature at a particular point on the test panel will reach a maximum some time after the line source has passed [138].…”
