Hey Vortex
Always wondered, what is the software you have used to capture the pulses?
Is it a homemade Ipad scope, with a simple IR receiver circuit connected to the 3.5mm audio jack

Or is that actually your output from a real scope?

I have 1 too and it works 100% ,
The Alp is rather strong like a forcefield around your car!

I imagine he's using an Optical Photo-IR diode ckt. (see Guys of Lidar) & capturing the PRR on a Laptop digital oscilloscope app.
