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.
 

Thread 'Analog power supply output question'

I'm setting up an analog power supply. I have the transformer bridge and filter capacitors so far. The transformer puts out 30 volts. I am currently using two parallel power transistors and a variable resistor to set the output. It also has a meter to monitor voltage. The question is this. How do I set up a single transistor to remove whats left of the ripple after the filter capacitors. It has to vary along with the control transistors to be constant in its ripple removing. The bases of the...
