What is the scan Lidar?

Lidar scanning is a means of detecting the characteristics of the object using laser light rays. Lidar, the abbreviation for the detection and extent of light, works on a similar principle to the radar, except that instead of radio waves radio uses ultraviolet, almost infrared or visible light. When scanning Lidar Laser, he fires on the target of the light pulses formula and when the light is reflected from the target, its properties are analyzed, providing information about the object that reflects it. Lidar scanning was used in many areas, including meteorology, geology and films. Photons of visible and ultraviolet light have only a few hundred nanometers, while radio emissions have a wavelength of at least 1 millimeter, and most modern radars release radio waves with a wavelength of at least 10 millimeters. The detection system based on electromagnetic radiation emitting in general cannot detect objects less than the wavelength of its own emissions, and thus Lidar is effective for the tasks thatrequire detection of small objects or details. Lidar is also more effective than a radar for detecting non -metallic objects, which often reflect radio waves badly and in some cases do not reflect them at all.

Lidar scan commonly uses meteorologists to study atmospheric conditions and weather patterns. There are several different methods, allowing Lidar to detect things such as clouds, chemical composition of the atmosphere area or wind speed. This information is used for purposes such as weather monitoring and prediction and monitoring wind conditions around wind turbines generating electricity, so that turbines can be modified to maximize power and prevent the equipment from damaging.

Idar lketing can also be used to study the topography of the country for fields such as geology, seismology and archeology. Lidar can produce high -resolution maps because of its ability to detect Malor fine off -road features, recognize small differences in height and small changes over time and precisely scan the terrain covered with thick vegetation. This allows geologists to study fine changes on the Earth's surface. In this way, the movement of geological disorders and glaciers, which move at extremely slow speeds, can also be measured. Lidar scanning can also be used to detect fine functions and changes in the soil, which is useful for soil surveys.

Lidar scan can also provide three -dimensional imaging in other areas. Lidar based on Lidar called 3-D Laser Scanner Time creates a three-dimensional image of the object in almost the same way as Lidar is used to measure topography, bombing the object with fast light pulses and measurement, as measuring, it takes a way for reflected photons to return. This can produce an accurate image faster than some other forms of three -dimensional display. Lidar is used in this way for purposes such as measurement and quality control in industry; Creating three -dimensional images and mOdel for movies, television and video games; And accurate exploration of historical artifacts and works of art.
