Lightweight and Compact Topo-Bathymetric Airborne Laser Scanner with Online Waveform Processing and Full Waveform Recording • high accuracy ranging based on echo digitization and online waveform processing with multiple-target capability • concurrent comprehensive full waveform storage for all measurements • high spatial resolution due to measurement rate of up to 100 kHz and high scanning speed of up to 100 scans/sec • integrated digital camera (optional) The distance measurement is based on the time-of-flight measurement with very short laser pulses and subsequent echo di digitization and online waveform processing. The laser beam is deflected in an elliptic scan pattern and hits the water surface at an incidence angle with low variation. • integrated inertial navigation system (optional) The scanner carries out laser range measurements for surveying of underwater topography with a narrow, visible green laser beam, emitted from a pulsed laser source. Subject to clarity, at this particular wavelength the laser beam penetrates water enabling measurement of submerged targets. • designed for combined topographic and bathymetric UAV-based survey The RIEGL® VQ-840-GE is a fully integrated compact airborne laser scanner for combined topographic and bathymetric surveying. Its compact and very lightweight design facilitates integration into UAVs. The system can be offered optionally with an integrated and factory-calibrated IMU/GNSS system and an optional camera. • compact, lightweight and robust housing compliant with stabilized platforms The VQ-840-GE can be complemented with an inertial navigati navigation sensor for subsequent estimation of the instrument’s location and orientation. As further option a high-resolution digital camera can be integrated to supplement the data gained by the laser scanner. The rugged internal mechanical structure together with the dustand splash water proof housing enables long-term operation on airborne platforms, especially UAVs. Typical applications include • coastline and shallow water mapping • river surveying • repeated survey of water reservoirs visit our website www.riegl.com Airborne Laser Scanning
