Fig. 1. a) cross section of a slab with solidification cracks, b) Reflection configuration: Excitation laser and detection laser are arranged at the same spot. Ultrasonic waves are induced in the sample by an pulsed excitation laser (red), propagate through the sample and get reflected or scattered by interfaces (cracks, blowholes,…). The detection of reflected and scattered ultrasonic waves is realized with a two wave beam mixing interferometer (green). c) Transmission configuration: Excitation laser (red) and detection laser (green) are arranged at the opposite side of the sample.
