I just watched the video and am a little confused about the laser illumination. Does the laser have to be "aimed" at each object of interest or is it just laser illumination of the whole scene? The graphics suggest there's a laser point on each object, but that means it has to be aimed and thus follow the subject, right? Moreover many objects, like guitars, have complex oscillation modes so if you are "listening" to just "one point" on the surface, you're not picking up the sound from the other parts of the guitar which are oscillating differently.

The laser needs to be aimed at each point of interest. The system can track multiple laser points simultaneously with one pair of cameras, but there's a tradeoff with quality (because essentially the camera's field of view is being divided into slices, one for each laser point). So you've got a small number of virtual contact microphones you can point at a surface, not a video where you can see the vibration at each point.
