WebIn passive LiDAR systems, the time it takes to detect an object is dependent on many variables, such as distance, interrogation pattern, resolution, reflectivity, the shape of the object, and the scan rate. A key factor missing from the conventional metric is a finer definition of time. Lidar is an acronym of "light detection and ranging" or "laser imaging, detection, and ranging". It is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. It is sometimes called 3-D laser scanning, a special combination of 3-D scanning and laser scanning. LIDAR has terrestrial, airborne, and mobile appli… igntg cors
