Hello,

Unfortunately, I can't find any information about what is the best way to measure distances from 1 to 10 meters. Like Dwayne, I'd like to measure distances between vehicles.

I assume the use of a LASER diode is the way to go.

There is no need for high accuracy; plus/minus 10 centimeter is acceptable.

I was thinking about generate a laser pulse and, in the same time, have another element "looking" at the spot and mesuring the time between the "laser switch-on" and "I can see the spot".

How is it realised in those meters one can find in the stores?
