2. What is LiDAR Technology?

LiDAR stands for Light Detection and Ranging, a remote sensing method that uses laser light to measure distances and generate precise three-dimensional maps of surroundings. The basic principle behind LiDAR is similar to radar; however, instead of radio waves, LiDAR uses light waves. By emitting laser pulses and measuring the time it takes for these pulses to bounce back after hitting an object, LiDAR systems can calculate the distance to that object with remarkable precision.

Core Principles of LiDAR:

• Laser Emission: A laser source emits a pulse of light.
• Reflection: The light pulse reflects off objects in the environment.
• Detection: A sensor detects the reflected light.
• Time-of-Flight Calculation: The system measures the time interval between emission and detection, which is then used to calculate the distance to the object.
• 3D Mapping: By rapidly emitting multiple pulses across a scene, LiDAR generates a dense point cloud representing a 3D map of the environment.

LiDAR’s ability to operate in a variety of lighting conditions—including complete darkness—makes it an invaluable tool for autonomous systems and a host of other applications.

1. Laser Emission: The sensor emits a focused laser pulse into the environment.
2. Pulse Reflection: The pulse travels until it encounters an object, where it is reflected back towards the sensor.
3. Detection and Timing: A photodetector within the sensor captures the reflected pulse. The system calculates the time it took for the pulse to return.
4. Distance Calculation: Using the time-of-flight (ToF) principle, the sensor computes the distance to the object based on the speed of light.
5. Point Cloud Generation: By repeating this process thousands of times per second, the sensor creates a detailed 3D point cloud of the environment.
6. Data Processing: High-speed processors and AI-driven algorithms analyze the point cloud data to identify objects, classify them, and generate actionable insights for autonomous systems.
