1. LiDAR Sensor vs Distance Sensor Working Principles
Laser Distance Sensor (Single-Point Measurement)
- 용도 비행 시간 (TOF) or Phase-Shift methods to calculate the distance between the sensor and a target.
- Provides a single measurement point per trigger.
- Commonly used for linear measurements such as length, height, or thickness 탐지.
LiDAR Sensor (Multi-Point & Scanning)
- Uses laser pulses and rotating/oscillating mirrors to scan across an area.
- Collects thousands of measurement points per second.
- Builds 2D or 3D maps of environments, making it suitable for advanced navigation and environmental modeling.

자주 묻는 질문(FAQ)
What is the main difference between a LiDAR Sensor vs Distance Sensor?
A distance sensor measures a single point between the sensor and a target, usually for simple distance or level detection. A LiDAR sensor, on the other hand, scans across multiple points to generate 2D or 3D maps, making it suitable for robotics, navigation, and environmental mapping.
What is the difference in accuracy in LiDAR Sensor vs Distance Sensor?
Both technologies use laser-based measurement and can achieve millimeter-level accuracy. However, 레이저 거리 센서 typically offer higher precision at a single point, while LiDAR sensors provide broader spatial awareness with slightly lower per-point accuracy due to scanning speed and range.
Can a laser distance sensor replace a LiDAR sensor?
Not usually. A laser distance sensor is ideal for applications where only one measurement value is needed (e.g., thickness, level, height detection). A LiDAR sensor is required when an application demands mapping, obstacle detection, or multi-point measurements, such as in autonomous vehicles or robotics.
What industries use LiDAR sensors?
Autonomous driving – for navigation and obstacle detection.
Surveying & mapping – creating 3D terrain and building models.
Robotics – SLAM navigation and environment recognition.
Smart cities – traffic monitoring, security, and infrastructure planning.
어떤 산업에서 레이저 거리 센서를 사용하나요?
Industrial automation – conveyor belt detection, part positioning.
Logistics & warehouses – height measurement, pallet detection.
Construction – laser rangefinders for distance checks.
Agriculture – monitoring crop levels, silo measurement.
What is single-point measurement vs multi-point scanning?
Single-point measurement: A laser distance sensor gives one value per reading, such as the distance to an object.
Multi-point scanning: LiDAR sensors collect thousands of points per second, building a 2D line scan or a 3D point cloud.
Is LiDAR better than ultrasonic or infrared distance sensors?
Yes, in terms of accuracy, range, and reliability, LiDAR and laser distance sensors outperform ultrasonic or 적외선 센서. Ultrasonic sensors are cheaper but less precise, while infrared sensors are sensitive to environmental light. LiDAR and 레이저 센서 are more suitable for industrial and professional measurement tasks.
Do LiDAR sensors work indoors and outdoors?
Yes. Modern LiDAR sensors can operate both indoors and outdoors. 2D LiDAR is commonly used indoors for robotics, while 3D LiDAR is preferred outdoors for UAV mapping and autonomous vehicles. Outdoor performance depends on laser wavelength, range, and environmental conditions (fog, dust, rain).
How do I choose between a LiDAR Sensor vs Distance Sensor?
Ask yourself:
Do I need one precise point measurement? → Choose a distance sensor.
Do I need mapping, scanning, or obstacle detection? → Choose a LiDAR sensor.
Do I need both precision and environmental awareness? → Consider a hybrid solution or customized module.
Are customized measurement modules available?
Yes. Many manufacturers offer personalized and customized measurement modules to fit industry-specific needs, including:
Compact modules for UAVs or drones.
Long-range outdoor modules (100–200m).
OEM integration with RS232/RS485, CAN, or analog outputs.
