Description

The high-speed rotating mirror design ensures reliability and uniform point distribution across its entire wide field of view and at all flight altitudes. Based on RIEGL's proven Waveform-LiDAR technology, the system provides point clouds with the highest accuracy, excellent vertical target resolution, calibrated reflectance readings, and pulse shape deviation for unsurpassed information content on every single measurement. Excellent atmospheric clutter suppression yields clean point clouds with minimum efforts in filtering isolated noise points. The system is complemented by RIEGL's advanced acquisition and data processing software suite that utilises parallel computing (GPU) for fast data processing. The RIEGL VQ-780 II-S is designed to work with the latest Inertial Navigation (IMU) Systems, flight management systems, and camera options.
