LiDAR (Light Detection and Ranging) technology has become an essential tool in industrial automation, IoT (Internet of Things), transportation and logistics, and more. By providing non-contact detection and measurement, LiDAR systems enable advancements in object recognition, evaluation, and navigation. Among the key types of LiDAR systems are 1D, 2D, and 3D, each designed to address specific application needs.
1D LiDAR Systems
1D LiDAR systems, often referred to as linear measurement sensors, focus on a single point to determine distances to a specific object or reflector. These systems are ideal for simple distance measurement applications where precision is crucial.
1D LiDAR sensors, such as Wiseome's Mini LiDAR, are ideal for:
- Precise positioning of rack structures for pick-and-place operations
- Measuring distances to specific targets or reflectors
- Motion frequency detection as part of an IoT system
Key Features:
- Optimized measurement cycle times for reliable and precise long-distance measurements
- Thinnest optical structure (< 6mm) in the industry
- Industry-leading measurement range of up to 20m
- Exceptional accuracy of ±3mm
- Ability to detect rapid distance changes

2D LiDAR Systems
2D LiDAR systems expand on the capabilities of 1D sensors by capturing both distance and angle data within a single plane. Using rotating mirrors or other mechanisms, these sensors create a two-dimensional map of the environment. These sensors are suitable for:
- Object contour detection
- Area monitoring
- Vehicle profiling in toll systems
- Volume measurement systems
- Collision avoidance systems in automated guided vehicles (AGVs)
Key Features:
- Effective scanning ranges from 10 to 80 meters
- Multiple echo detection for enhanced environmental filtering
3D LiDAR Systems
3D LiDAR sensors provide the most comprehensive spatial data, offering measurements across three dimensions. There are two main approaches to 3D LiDAR:
- Multi-layer scanners: Devices like Sick's MRS1000 and LD-MRS series use multiple emitter-receiver pairs or clever optical designs to scan multiple planes simultaneously.
- Moving 2D scanners: By mounting 2D scanners on rotating or linear actuators, 3D scans can be created over time.
Key Features:
- Provides complete spatial awareness.
- Captures high-density data for precise modeling.
- Handles complex environments with varying angles and distances.
