LiDAR (/ˈlaɪdɑːr/, also LIDAR, or LiDAR; sometimes LADAR) is a method for determining ranges (variable distance) by targeting an object with a laser and measuring the time for the reflected light to return to the receiver. Lidar can also be used to make digital 3-D representations of areas on the earth’s surface and ocean bottom, due to differences in laser return times, and by varying laser wavelengths. It has terrestrial, airborne, and mobile applications.
Lidar is an acronym of “light detection and ranging” or “laser imaging, detection, and ranging”. Lidar sometimes is called 3-D laser scanning, a special combination of 3-D scanning and laser scanning.
LiDAR is a remote sensing technology. LiDAR technology uses the pulse from a laser to collect measurements. These are used to create 3D models and maps of objects and environments.
Types of LiDAR
Mechanical LiDAR (scanning LiDAR uses mechanical rotation to spin the sensor for 360-degree detection) – LS LiDAR, Olei.
Solid-State LiDAR
-Micro-electromechanical system (MEMS) technology in which a MEMS-based mirror moves to “scan” the environment – Blickfeld.
-Optical phased array (OPA) that deliver light pause to a different direction by adjusting the array and does not require sensor movement
-Flash Lidar technology works like a camera, delivering a flashlight to detect the whole surrounding area at once and analyzing the information with an image sensor – LeddarTech.
Using a unique combination of two custom chips: one vertical-cavity surface-emitting laser (VCSEL) chip for firing the lasers, and one photon avalanche diode (SPAD) chip for detecting the lasers when they bounce back. Put these two chips together, and you get a “multi-beam flash lidar – Ouster
