Pulse collision avoidance
« on: November 27, 2017, 08:34:48 AM »
Hello everybody,
I am currently re-working our trigger hard- and software and I was wondering about pulse collision avoidance schemes at high rep rates. Currently, we use either:
1) Standard continuous triggering, ignoring pulse collisions. Works okay up to ~5 kHz in our configuration.
2) Burst mode: One ToF fire, one ToF quiet/receive. Works well at all rep rates, but you always loose half of the time.
I suppose for the really high rep rates, burst mode is about the best we can do. But what about 1 to 10 kHz? Do you have any recommendations of pulse collision avoidance schemes? I suppose we could trigger at, say, 5 kHz and reduce to 4.5 kHz every time the ToF come close to N x LI (laser interval). But is that the best we can do? What do you use? What would be an ideal scheme?
Thanks,
Daniel
