"Because it measures in the infrared, it even works in the /dark/"

No, because it's an active rather than passive light sensor, it works in the dark.

Edit: also, the fact that you can see a green dot heavily implies the sensor is operating in the green wavelengths, not in the infrared, but that's secondary.

It uses LiDAR. The green dot is an aiming laser for the human, and is calculated from the LiDAR result.

You can use the green part of the spectrum for LiDAR. It’s what they use for bathymetric LiDAR.

Regardless, the green dot is produced by a laser, not the lidar module, as shown in the video.

While you are right about the active light sensor, it is likely that the sensor really works in the infrared.

The green laser beam must be in addition to the infrared beam, with the purpose of allowing a human to choose the aiming spot.

They say the green drop is actually lowered after ranging, so the user knows how to aim with the gravity-induced drop. Pretty cool :)
