Description

The new RIEGL VQ-840-G is a fully integrated compact airborne laser scanner for combined hydrographic and topographic surveying. The system is offered with an integrated and factory-calibrated GNSS/IMU system and can be complemented with an optional camera or IR rangefinder. The VQ-840-G is a compact and lightweight LiDAR system to be installed on various platforms including UAVs.

The scanner carries out laser range measurements for high resolution 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.
