Dual-mount lidar system enables collection efficiency

November 7th, 2019, Published in Articles: PositionIT

Teledyne Optech has released the next evolution of its Galaxy platform, the T2000. A compact lidar-mapping sensor provides a feature set for maximum collection efficiency and point density, and is the next step in the evolution of modern aerial surveying. Coupled with a new G2 mounting system, the system leverages its compact size to co-mount two sensors over a single aircraft portal, making it a flexible commercial lidar system. The T2000 has a 2 MHz laser emission rate directed fully to the ground by a new high frequency, programmable scanner for effective point distribution. Combined with the company’s patented SwathTrak capability, the system is capable of maintaining fixed-width data swaths in mountainous terrain via a dynamic field-of-view (FOV), enabling far fewer flight lines and more equidistant point spacing compared to fixed-FOV sensor designs. The Galaxy T2000 also has a much narrower beam divergence at 0,16 mrad (1/e), producing higher energy density within the laser footprint. This has the advantage of further increasing ground detection in heavily forested environments. Furthermore, as point densities increase, the smaller beam footprint becomes a necessary requirement for superior target and model resolution.
