LIDAR (Light Detection and Ranging)'s an optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant target. The prevalent method to determine distance to an object or surface's to use laser pulses. Like the similar radar technology, which uses radio waves, which's light that isn't in the visible spectrum, the range to an object's determined by measuring the time delay between transmission of a pulse and detection of the refl… (More on Lidar)
