Chronos User Discussion / Re: Frame straddling for PIV
« on: October 13, 2023, 02:17:12 PM »
Ok, I was able to get a response from Mike Tymofie at Krontech. Here's the frame straddling times for the two Chronos cameras:
Chronos 1.4 - 5.56 us
Chronos 2.1 - 6.67 us
These are calculated times, according to him. I am not sure what that means but I'd like to try it in practice. At least now I can plan my PIV experiments, and I believe these times are acceptable for moderate flow speeds (say, up to ~100m/s or so depending on magnification and other aspects). Say, at 100m/s a particle would move 0.7mm in 7us. If we're doing cross-plane Stereo PIV, that is as much you would want (about 25% of the ~3mm light sheet). So, unfortunately, no supersonic flows
I'll let you know more when I get my hands on one and I have a laser available to test it.
Hope this helps somebody in the future!
