LIDAR Overview How it works Usages of LIDAR Topics
LIDAR What is it?
LIDAR optical remote sensing technology laser scanner and optics photodetector and receiver electronics position and navigation systems Overview
LIDAR How does it work?
LIDAR measuring the time delay between transmission of a pulse and detection of the reflected signal gives range measuring light reflected back identifies surface types laser returns more detailed results than radar Light Amplification by Stimulated Emission of Radiation How it works
LIDAR What can it be used for?
