LIDAR Explained: What is LIDAR? How LIDAR Works? LIDAR vs RADAR

In this video, the overview of LIDAR technology has been given. So, in this video you will learn, What is LIDAR, How LIDAR works, Difference between RADAR and LIDAR and different applications of LIDAR. What is LIDAR? LIDAR is the acronym of the term Light Detection And Ranging. In this technology light source or light, waves are used to measure the distance between the objects. How LIDAR Works? Most of the LIDAR system works on the time of flight principle, where laser in pulsed form is targeted onto the object and the reflected or the scattered pulse is measured using the detector. By measuring the time difference between the transmitted and reflected pulse, the distance between the objects can be calculated. Now, as the LASER beam has very low divergence (Less expansion with travel distance)and very short wavelength, it can also be used for scanning of the object. (For 3D mapping and surface scanning applications) LIDAR vs RADAR 1. RADAR uses radio waves (Longer Wavelength), while LIDAR uses Light waves (Shorter Wavelength). 2. LIDAR is more accurate than RADAR as it uses shorter wavelength. 3. RADAR can work in harsh environments like fog, rain, and snow, while LIDAR has limited usability in such environments. 4. While RADAR is used in applications where detection distance is important but not the exact size and shape of an object, like in military applications. While LIDAR is used in applications where the detection of exact shape and size of the object is necessary. Components of LIDAR 1. LASER 2. DETECTOR 3. OPTICS and Rotating mechanism 4.
