Fastest way to trigger a single frame image from any time of camera

Hi All,

I'm looking at a setup that would have a hardware trigger that would send a signal to a camera to capture a single still image.

All the web cameras would be bound by their FPS so are not great, and DSLRs are 100-150ms.

I will be using a laser that when broken will need to take an image, this will happen every 5-6 seconds. The object will be going ~100mph and there is a TON of light available …
