Lidar is an acronym that stands for detection and range of light. It's basically like a measuring tape, except that it uses the speed of light to measure distance, rather than a physical object. Lidar means detection and range of light, and it's been around for a while. It uses lasers to detect objects and return them to the laser source, measuring the distance by timing the journey or flight of the light pulse.
LiDAR is different from technologies such as RADAR. LiDAR is short for light detection and range. In a nutshell, LiDAR consists of firing an invisible laser at its environment. LiDAR sensors then use the laser data to detect information about the shape of objects and their distance from you.
LiDAR stands for “Light Detection And Ranging” and, in fact, uses a laser to achieve its purpose. It sends lasers and measures the time it takes for them to return to the source and, in doing so, it can measure the distance and depth of objects using this “flight time”. LiDAR uses a light-sensing technique to calculate depth. It works by emitting pulses of infrared light and measuring the time they take to return after colliding with nearby objects.
The time between the output laser pulse and the reflected pulse allows the LiDAR sensor to calculate the distance to each object based on the speed of light. What does the LiDAR scanner do?
