LIDAR
LIDAR (Light Detection and Ranging) is a sensing technology that helps machines and vehicles "see" their surroundings by using laser beams to measure distances. Think of it like radar, but using light instead of radio waves. It's commonly used in self-driving cars, robots, and drones to create detailed 3D maps of their environment. When you see this term in resumes, it usually means the candidate has experience with sensors that help machines navigate and understand their surroundings. It's a key technology in autonomous vehicles, robotics, and mapping applications.
