VQ-880-GII / VQ-880-GH

Topo-Bathymetric Airborne Laser Scanning System with Online Waveform Processing and Full Waveform Recording

The VQ-880-GII / 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.
