Acoustics

At Los Alamos I measure things vibrate. Here, thin films and small sensors get played with sound, a laser reads how they ring, and we work backwards to how stiff they are and how tightly they're held.

Fig. 1. A polymer film, stretched like a drumhead and played with sound, while a laser listens to how it rings. Two of its notes are enough to tell how tight it is and how stiff.

Fig. 2. Small devices that turn vibration into voltage are hard to measure the same way twice, because they buckle. So we 3D-printed fixtures to hold them still.
