Ok, this is one thing that I don't understand. Why is laser so hard to pick up. I know that it is a narrow beam, etc. But I was playing with my tv remote and it doesn't matter where I point it, it turns the channel. Now if a low powered tv remote can bounce all around and get picked up by the cable box, why can't detectors detect lidar just as good. I mean Lidar has to bounce around like infrared light of a remote.
