The RIEGL miniVUX-3UAV is an extremely lightweight airborne
laser scanner, designed specifically for integration withUAS/UAV/RPAS. The sensor offers a selectable 100 kHz, 200 kHz,and 300 kHz laser pulse repetition rate (PRR). With 300 kHz PRR,
it provides up to 100,000 measurements per second at 120° FoVand thus a dense point pattern on the ground for UAV-based
applications that require the acquisition of small objects.
The small and sophisticated design of the stable aluminum housing
offers various integration possibilities with platforms that offer restricted
space or payload capabilities. The 360° field of view allows
complete acquisition of the environment.
An easy-to-remove SD card for data storage, and/or the option for
streaming the scan data via LAN-TCP/IP interface, in combination withthe modest power consumption of the scanner, enable straight-forward
integration with most UAS/UAV/RPAS types.
The RIEGL miniVUX-3UAV makes use of RIEGL’s unique Waveform-LiDAR
technology, allowing echo digitization and online waveform processing.
Multi-target resolution is the basis for penetrating even dense foliage.
As a further special feature, the wavelength is optimized for the measurement of snowy and icy terrain.
In addition to the stand-alone version of the miniVUX-3UAV, RIEGL alsooffers fully-integrated system solutions.

Typical applications include• Agriculture & Forestry• Glacier and Snowfield Mapping• Archeology and Cultural
Heritage Documentation• Construction-Site Monitoring• Landslide Monitoring
