Technical details and manufacturing context for LiDAR Sensor

Definition

A LiDAR (Light Detection and Ranging) sensor is an active remote sensing instrument that emits laser pulses toward targets and measures the time it takes for the reflected light to return to the sensor. By calculating these time-of-flight measurements and combining them with position and orientation data, the sensor generates highly accurate three-dimensional point cloud representations of objects and environments. Modern LiDAR systems operate at high frequencies, enabling real-time mapping and object detection capabilities across various applications including autonomous vehicles, robotics, surveying, and industrial automation. This directory entry covers a generic LiDAR sensor device intended for integration into larger systems. The sensor's core components include semiconductor laser diodes, optical lenses, photodetectors, and an aluminum housing. Key parameters listed are reference ranges that must be verified for the specific model and application. The maximum range is 100–200 meters, with a range accuracy of ±2 centimeters. Angular resolution is 0.1–0.5 degrees, and the horizontal field of view is 360 degrees. The measurement rate is 300,000–600,000 points per second. The laser wavelength is 905 nanometers. Operating temperature ranges from -40 to 85 degrees Celsius, and power consumption is 10–15 watts. Supply voltage is 9–36 V DC with reverse polarity protection. The ingress protection rating is IP67 per IEC 60529, indicating dust-tight and waterproof characteristics. Weight is 1.5–2.5 kilograms without mounting bracket, and dimensions are 120 mm diameter by 80 mm height. Data interface is Ethernet using UDP packets per IEEE 802.3. These specifications are typical for industrial LiDAR sensors but must be confirmed with the manufacturer for the exact model. The sensor is designed for use in environments where accurate distance measurement and 3D mapping are required. It is not a complete system but a component that requires integration with power, data processing, and mounting. Always verify model-specific values and standards with the legal manufacturer or supplier before procurement or deployment.

Working Principle

LiDAR sensors operate on the principle of time-of-flight measurement. The system emits short, focused laser pulses from a transmitter. These pulses travel through the air until they encounter objects in their path, where they reflect back toward the sensor. A photodetector receives the reflected pulses, and precise timing electronics measure the elapsed time between emission and reception. Using the known speed of light, the system calculates the distance to each reflection point. By scanning the laser beam across a field of view (typically using rotating mirrors, MEMS mirrors, or solid-state scanning techniques) and combining distance measurements with position/orientation data from integrated IMUs and GPS, the sensor builds a detailed 3D point cloud representation of the surrounding environment.
