Can the LakiBeam 1L be synchronised to allow the use of multiple units without interference with each other?

Hi Stephanie
I would think any radar would interfere with any other radar in the same frequency band especially with the statement

I think you would have to shut down completely (power off) any radars not in use at that moment in time but I don’t know if that would be feasible.

I just had a look at the specs for that device. It is basically optical (pulsed laser) so the interference might be minimal. Scanning is done with a rotating mirror and covers 270º of the complete circle which seems to contradict the statement above regarding blind spots. The degree of interference would depend somewhat on the target. If this reflected some of the laser beam back to another radar unit with the mirror pointing in the right direction I think you would expect some interference. Or if any mirrors were pointing at each other you could expect a lot of interference.

I think you would have to somehow synchronise the instantaneous position of the mirrors but I can’t see just ow you would do that.

A bit of a problem.
Cheers Bob

Hi @Stephanie295269

Welcome to the forum!

As Bob mentioned, each unit would interfere with the others, you would need to have them sequenced so that only one unit is going off at once, or offset the line of sight of each unit so that the output of one isn’t received by another as depicted in the user manual.

Hi Dan

Nice old mix up if you have several units rotating with moving targets. Nice one to sort out.
Cheers Bob

Hi Bob,

I envision that if you weren’t aware of this that it would be a nightmare to try and troubleshoot.

Hi Stephanie,

From LiDAR’s I’ve had experience with (and it might be different with this one).

You can set the driver to only measure specific areas.
(I believe that is what Team Bumblebee did in the Robot X competition: Bumblebee ASV 4.0 | Bumblebee)

Powering off is a possibility but the driver/SDK allows for the laser to be enabled/disabled whenever.

If you require somewhat simultaneous measurements, a physical mask could be made to cover the sensor and the points from other units.
