This particular camera/light source combination makes a movie by taking a picture sometime after the pulse of light has been output. By varying the time delay from the pulse to the picture, it can stitch together the pictures into the semblance of a movie. A neat idea, it relies on the fact that the path & time-of-flight of the pulse does not change at all, pulse after pulse.
If the pinch DPF’s pinch is absolutely repeatable, pulse after pulse, a similar method could be used. However, from my reading of the results, it can not be repeated that well.
Still, a technique like this might offer some insight into the processes taking place in the chamber. Here’s hoping that, if it’s applicable, they use the idea.
