The system is offered with integrated and factory-calibrated high-end GNSS/IMU system and up to two cameras. The design allows flexible application of these components to meet specific requirements. Complemented by a RIEGL data recorder, the RIEGL VQ-880-GH LIDAR system can be installed on various platforms in a straightforward way. The RIEGL VQ-880-GH carries out laser range measurements for high resolution surveying of underwater topography with a narrow, visible green laser beam, emitted from a powerful pulsed laser source. Subject to clarity, at this particular wavelength the laser beam penetrates water enabling measurement of submerged targets. The distance measurement is based on the time-of-flight measurement with very short laser pulses and subsequent echo digitization and online waveform processing. To handle target situations with most complex multiple echo signals, beside the online waveform processing the digitized echo waveforms can be stored on the RIEGL solid state data recorder for subsequent off-line waveform analysis. The laser beam is deflected in a circular scan pattern and hits the water surface at a nominally constant incidence angle. The VQ-880-GH comprises a high precision inertial measurement sensor for subsequent precise estimation of the instrument’s exact location and orientation. Two high-resolution digital cameras and an additional infrared laser scanner are integrated to supplement the data gained by the green laser scanner. The rugged internal mechanical structure together with the dust- und splash water proof housing enables long-term operation on airborne platforms. Typical applications include • coastline and shallow water mapping • acquiring base data for flood prevention • measurement for aggradation zones • habitat mapping • surveying for hydraulic engineering • hydro-archeological-surveying visit our website www.riegl.com
