From: Evaluation of pitting corrosion by dynamic speckle pattern analysis
The time history speckle pattern (THSP), formed by tracking 800 random points all over the collection of 500 speckle patterns of the sample (image datapack points). The results at (a) \(\hbox {t} = 10 \,\hbox {min}\), (b) \(\hbox {t} = 20 \,\hbox {min}\), (c) \(\hbox {t} = 30 \,\hbox {min}\) after the experiment starts, are shown.
