The discussion centers on the advancements in coherent two-photon lidar technology and its implications for lidar range and precision. Participants question whether this method allows lidar to operate effectively over distances greater than a few kilometers or if it simply enhances measurement accuracy. The conversation touches on the fundamental principles of lidar, including the inverse square law and comparisons to radar technology. There is a sense of uncertainty regarding the practical applications and theoretical aspects of the technology. Overall, the breakthrough suggests potential for improved lidar performance, but clarity on effective range remains a topic of inquiry.

Does this mean lidar is now effective at ranges over a few kilometers? Or does it mean lidar measurements are now more precise?

If lidar effective ranges are greater, what would be the current range using the coherent two-photon method?
LIDAR obeys the inverse square law no? It's really much like RADAR isn't it? It's basically to do with intensity yes? The article seems to me very theoretical, but I guess that's QM (read: Greek) for me.

Nvm. I'm surely in over my head.
 
I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
