RedTail LiDAR Systems RTL-400

MEMS-based LiDAR system designed for small UAVs

The RedTail LiDAR System is a MEMS-based LiDAR system designed specifically to be flown on small UAVS up to 400 ft. The RTL-400 evenly distributes all points to the ground, generating high-resolution, highly accurate point clouds. Incorporating technology licensed from the U.S. Army Research Laboratory, the RTL-400 has a line scan rate of 400 lines per second, a PRR of 400,000 pulses per second, and offers a 3D line scan mode and a 2D raster scan mode, which can be selected on the fly.

RedTail LiDAR Systems' RTL-400 was designed specifically to provide high-resolution 3D images of objects on the ground from small drones flying at an altitude up to 400 feet.

Developed with technology licensed from the U.S. Army Research Laboratory (ARL), the RTL-400 provides unique scanning capabilities for a wide range of applications – from precision agriculture to construction site monitoring and management.

The RTL-400 incorporates an innovative microelectromechanical system (MEMS) mirror-based laser scanner that rapidly and evenly distributes laser pulses to the ground, moving side-to-side 400 times each second.  This rapid line scan rate, coupled with a laser pulse rate of up to 400,000 pulses per second, yields point clouds that are unprecedented in resolution and density.

Unlike other LiDAR systems, the RTL-400 can be operated in two scanning modes.  In addition to the line scan mode, the RTL-400 offers a 30 x 30-degree raster scan mode for “stand and stare” missions.  The scanning mode can be selected on the fly, providing drone operators unmatched operational flexibility when planning and flying their missions.
