Types of Laser Sensors for RTK Systems
Choosing the right sensor depends on your specific application. The most common types include:
- Flugzeit (ToF) Sensors – Measure distance by calculating the time it takes for a laser pulse to reflect back to the sensor. Suitable for medium- to long-range measurements, with fast response times.
- Phase-Shift Sensors – Determine distance by measuring the phase difference between emitted and reflected laser signals. Offer higher precision over longer distances than ToF-Sensoren, ideal for surveying and mapping applications.
- LiDAR Sensors – Emit multiple laser pulses to scan an environment and create high-resolution 3D maps. Widely used in drones, autonomous vehicles, and industrial environment scanning. Handle dynamic environments with moving objects or obstacles.
To make it easier to compare their strengths and applications, here’s a detailed comparison:
