laser ranging systems
In the 1950’s a small group of students and researchers, working at Princeton
University under Robert H. Dicke, probably first gave substance to the concept of what
would become the technique of optical laser ranging. In attempt to probe the
fundamentals of gravity, they suggested that powerful, pulsed searchlights on the earth be
used to illuminate optical corner retroreflectors placed upon an orbiting artificial earths
satellite’s motion by photographing its position against the background …

industrial machine tool control. A laser ranging system is a distance-measuring device
that operates by transmitting a short high power pulse toward the target. A photodetector
in the ranging system receives a reflection of the pulse. By knowing the time interval
required for the signal to travel from the transmitter to the target and back to the receiver,
it is possible to calculate the distance from the ranging system to the target.
