Advances in laboratory modeling of wave propagation

Laboratory studies of ultrasonic wave propagation can serve as either scaled modeling of challenges in seismic imaging, or as a way to investigate fundamental advancements in wave propagation. Particularly non-contacting laser ultrasonics provides tremendous opportunities toward both mentioned purposes, because the laser acquisition allows for automated scanning, a small source/receiver footprint and does not suffer mechanical ringing of traditional contacting ultrasonic sensor. Here we present calibration measurements of a new two-component laser receiver, as well a novel way of scaled modeling with structures made in glass.
