Leddar
LEDDAR (Light-Emitting Diode Detection And Ranging) is a proprietary technology owned by LeddarTech. It uses the time of flight of light signals and signal processing algorithms to detect, locate, and measure objects in its field of view. Technology. The Leddar technology is like a light-based radar that sends very short light pulses of invisible light about 100,000 times per second to actively illuminate an area of interest. The sensor captures the light backscattered from objects (either fixed or moving) over its detection area, and processes the signals to precisely map their location and other attributes. The data  is compiled thousands of times per second, providing up to a few hundred frames per second and offering accurate and reliable information even in adverse weather and lighting conditions. The multi-channel sensor also provides lateral discrimination of detected objects and this feature, with 3D measurements, provides the basis for object tracking. See also.
