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 …showed first 75 words of 303 total…

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. ------------------------------------------------------------------------ **Bibliography**
