LIDAR is a method of using focused light beams to detect distant objects. It works very much like RADAR and in fact the mnemonic “LIDAR” was initially a fusion of the words “RADAR” (Radio Detection And Ranging) and “Light”.Ī more common definition of “LIDAR” is Light Inspection, Detection and Ranging, this more accurately defines LIDARs role in inspection applications. Some publications use the letter “L” in “LIDAR” to mean “Laser” although a LIDAR unit can be built using light sources other than a laser. LIDAR functions by sending out a light beam and measuring its reflected signal. Several aspects of the signal are measured including the light intensity and angle. These measurements can be used to calculate the distance to the reflecting object as well as some information regarding its reflectivity. In many applications the light beam is moved or scanned to get several points of reflection, this data is often displayed in a three dimensional array known as a “point cloud”.
