VZ-400 3D Laser Scanner

The V-Line® 3D Terrestrial Laser Scanner RIEGL VZ-400 provides high speed, non-contact data acquisition using a narrow infrared laser beam and a fast scanning mechanism. High-accuracy laser ranging is based upon RIEGL's unique echo digitization and online waveform processing, which allows achieving superior measurement capability even under adverse atmospheric conditions and the evaluation of multiple target echoes.

The line scanning mechanism is based upon a fast rotating multi-facet polygonal mirror, which provides fully linear, unidirectional and parallel scan lines. The RIEGL VZ-400 is a very compact and lightweight surveying instrument, mountable in any orientation and even under limited space conditions.

Modes of Operation

  • Stand-alone data acquisition without the need of a notebook, basic configuration and commanding via the built-in user interface
  • Remote operation via RISCAN PRO on a notebook, connected either via LAN interface or integrated WLAN
  • Well-documented command interface for smooth integration into mobile laser scanning systems.
  • Interfacing to Post Processing Software

User Interfaces

  • Integrated Human-Machine Interface (HMI) for stand-alone operation without computer
  • High-resolution 3.5" TFT color display, 320 x 240 pixel, scratch resistant cover glass with anti-reflection coating and multi-lingual menu
  • Water and dirt resistant key pad with large buttons for instrument control
  • Loudspeaker for audible signaling of messages by voice

1 With Online Waveform processing - Rounded Values 
2 With Online Waveform processing - Rounded Values 
3 With Online Waveform processing - Typical values for average conditions. Maximum range is specified for flat targets with size in excess of the laser beam diameter, perpendicular angle of incidence, and for atmospheric visibility in excess of 23 km. In bright sunlight, the operational range is considerably shorter than under an overcast sky.
