Would that high speed camera do the job?

A while ago I read about the advantage, an ultra high speed motion camera would have for DPF research.

I stumbled upon this intriguing presentation and would like to bring that to your attention.

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.

I thought that all frames were taken from the same pulse of light, wondering only how the light reaches multiple sensors in that short time.
I should have listen more carefully.
