Lidars can interfere but somewhat less than other types of active sensors. First of all, the detector only needs to be on for a microsecond or two, and it's unlikely for two sensors to be scanning at the same microsecond. Second, laser spots are fairly small and unlikely to overlap. Finally, there are techniques to further get rid of crosstalk, such as coded random pulses with a matched filter.

- Animats 7y agoLIDARs for volume use should add a few microseconds of random (not pseudorandom) jitter to the outgoing pulse time. That will prevent multiple interfering scans from different units from all synchronizing. You may still get blinded on one scan, but not all of them.
