Time-of-Flight (ToF) LiDAR is a remote sensing technology that measures distance by calculating the time it takes for a laser pulse to travel from the sensor to an object and back. By emitting rapid laser beams and detecting their reflections, ToF LiDAR generates precise 3D point clouds of the surrounding environment. This method enables high-resolution, real-time depth mapping, making it ideal for applications requiring accurate spatial awareness, such as autonomous vehicles, robotics, and augmented reality.

ToF LiDAR systems can be categorized into different types, including mechanical LiDAR (which uses rotating mirrors for wide-area scanning), solid-state LiDAR (with no moving parts for improved durability), and flash LiDAR (which illuminates the entire scene in a single pulse). Common use cases span autonomous driving (for obstacle detection and navigation), industrial automation (for object recognition and logistics), and mapping/surveying (for high-precision terrain modeling). Due to its reliability and fast response time, ToF LiDAR is a key technology in advanced sensing and automation.
