Waveform Processing Airborne Laser Scanning SystemRIEGL VQ-580 II®

••high accuracy ranging based onRIEGL Waveform-LiDAR technology••high laser pulse repetition rateup to 2MHz••measurement rate up to1,250,000 measurements/sec••perfectly linear and parallelscan lines••wide field of view of 75°••excellently suited
to measure on snow & ice••interfaces for up to 5 optional
cameras••mechanical and electrical interface
for IMU/GNSS integration••removeable storage card andintegrated Solid State Disk (SSD)
for data storage

In further development of the RIEGL VQ-580 Airborne Laser Scanner
Series – the RIEGL VQ-580 II presents itself in a completly new designthat successfully takes up the already proven qualities and leads
them to a new standard of performance and user-friendliness.
Its new sophisticated design allows to further reduce the overall weightand enables the seamless integration into stabilized platforms, e.g.
standard gyromounts, and also into even small hatches. The scanneris well suited for the use in manned aircrafts like helicopters, small fixedwing aircrafts, or ultra-light planes.
Based on RIEGL‘s proven Waveform-LiDAR technology, the VQ-580 II
provides highly accurate point clouds, excellent vertical target resolution, calibrated reflectance readings, and pulse shape deviation for
unsurpassed information content on each single measurement. Witha measurement rate of up to 1,250,000 measurements/second andan extremely wide field of view of 75°, the scanner offers itself as thefirst choice for airborne surveying applications like corridor mapping,city modeling, and agriculture & forestry. The laser wavelength makes it
especially suited for measurements on ice and snow.

••compact, & lightweight design••compatible with stabilized
platforms and even small hatches••seamless integration andcompatibility with other RIEGL ALS
systems and software packages

An easy to remove CFast® storage card and an integrated Solid State
Disk and/or the option for streaming the scan data via LAN TCP/IP interface are provided for data transfer and storage.

Typical applications include••Corridor Mapping••Agriculture & Forestry••Especially suited forGlacier Mapping andSnowfield Mapping••Moist Grassland Mapping••City Modeling

3) The maximum range is specified for flat targets with size in excess of the laser beam diameter, perpendicular angle of incidence, and for atmospheric visibility of 23 km.
Range ambiguities have to be resolved by multiple-time-around processing.
4) Typical values for max. effective FOV 75°, additional roll angle ± 5°5) Nominal Ocular Hazard Distance (NOHD) and Extended Nominal Ocular Hazard Distance (ENOHD), based upon MPE according to IEC 60825-1:2014,
for non-persisting beam viewing (less than 600 laser pulses within a time period of 10 s) and non overlapping beam footprints.
NOHD and ENOHD increase when number of laser pulses exceeds this limit (persistent viewing).
6) If more than one target is hit, the total laser transmitter power is split and, accordingly, the achieveable range is reduced.
