LiDAR is at home in the fields of drone technology, automation, and Industry 4.0. The abbreviation LiDAR stands for „Light Detection and Ranging“. It is a technology that works with laser light to very accurately measure the distance to an object or surface.
A LiDAR system emits short light pulses which strike surfaces and are reflected back. The time taken for the light to travel there and back is measured. The system then calculates the exact distance from this. Many such measurements together create a very detailed digital image of the surroundings – similar to a 3D map.
A vivid example: drones with LiDAR scan forests or construction sites. This can be used, for example, to determine how high buildings are, how densely a forest is growing, or what the shape of an area of land is. In automation, LiDAR sensors help self-driving cars to detect obstacles early and react safely.
LiDAR's precise data helps make processes safer, more efficient, and more sustainable. Many innovative applications in industry and research would not be conceivable without this technology.
