RIEGL VUX-3HA High-Performance LiDAR Sensor
Price Available Upon Request
The RIEGL VUX-3HA is a high-performance LiDAR sensor for kinematic laser scanning, offering measurement rates up to 3 million measurements/sec, scan speeds up to 400 scans/sec, 3 mm accuracy, 2 mm precision, and a 360° field of view. Its compact 3.2 kg design combines RIEGL waveform processing technology, multiple-target capability, GNSS/IMU interfaces, and internal SSD storage for mobile road and rail mapping applications.
Product Overview
The RIEGL VUX-3HA is a high-performance LiDAR sensor designed for kinematic laser scanning. It combines an effective measurement rate of up to 3 MHz with an ultra-fast scanning speed of up to 400 scans per second, supporting high platform speeds and efficient data acquisition while maintaining a high level of point-cloud detail.
The sensor uses RIEGL’s pulsed laser ranging technology based on echo signal digitization with subsequent online waveform processing. This supports reliable measurements under adverse atmospheric conditions and provides effective discrimination of multiple target echoes.
Each measurement point can also include additional attributes such as range-independent reflectance and calibrated amplitude, providing information that can be used for classification and further AI-based processing.

Integrated Interfaces and Data Storage
The VUX-3HA provides interfaces designed for integration into mobile and kinematic mapping systems.
These include:
- Mechanical and electrical interface for external IMU
- Electrical interface for GNSS data string
- 1PPS synchronization pulse interface
- LAN TCP/IP
