I was surprised how much some of those shots resemble the effects you see in video games physics simulations and online "toy" physics sandboxes. I figured the real world would be more noisy but these results are quite uniform and beautiful. I'll have to give our physics modeling more credit from now on!
Based on the last shot, could potentially be useful for diagnosing potential failures due to metal fatigue - the kind of vibrations that you may be able to hear, but can't see. Not sure if that's the intent, but that's what jumped out at me...
I love ultra high speed video. Just about any motion is more interesting at that speed, even simple walking. But my favorite is watching water balloons explode: <a href="http://www.youtube.com/watch?v=0sLxuSN2UnQ" rel="nofollow">http://www.youtube.com/watch?v=0sLxuSN2UnQ</a>
Discovery has a series called "Time Warp" which explores many scenarios shot at very high fps.<p><a href="http://dsc.discovery.com/tv/time-warp/episode/episode.html" rel="nofollow">http://dsc.discovery.com/tv/time-warp/episode/episode.html</a><p>E.g.: <a href="http://www.youtube.com/watch?v=X0-TbUUXDtM" rel="nofollow">http://www.youtube.com/watch?v=X0-TbUUXDtM</a>
Curiously, most of the vibrations shown are such that you <i>can hear</i> in a very concrete terms.<p>In banging a barrel or a cymbal you can certainly hear the fluctuations on the metal surface. But you don't get a proper visual of how the sound actually forms until you see it on the video; when you do, it will just fit.
Slightly OT (or is it), but it's an ad for Fluke - probably the best test gear you can get IMHO yet under-advertised. It's good to see a good company getting with the times.
