I'm just looking for something that can tell me the difference between two things. There is time for precalibration, and time is not that big of a deal, as long as it works. Does anyone know if I put two ultralsonic range finders pointed at each other, would that work? I thought it might not...

The required acquisition time is probably a couple seconds. ideally should reach 10 seconds. There is time for precalibration, could you tell me what article in the Elektor you saw?

I was thinking along the lines of a laser beam emitting from the moving object, it can point to the receiving fixed point where there is a receiver, and that receiver can figure out the distance...is this something you're thinking about?

I may be a little unclear but what I mean is, is there maybe something that has a receiver on the other end that would do distance sensing?

Thanks! That was really helpful, do you know of something like this that would sense a particular item or a spot? Because I have a fixed point and then a point in motion so if I were to have the sensor on the point in motion I would need to find a way to point it in that direction, with this...

Also it the signal doesn't need to penetrate through anything, air is the only thing in between these devices.

I need it to be able to tell me the distance between two specific points, one may be a mobile location. The general range would be from 1 meter to 100 meters. I looked into LIDAR and RADAR but I'm not sure about RADAR because it seems like you the two objects need to be very far apart for it to...

Hey guys, do any of you know of a transmitter/receiver device that can let you know the distance between them? I really need some help fast and would really appreciate it!
