4D leveraged ten years of MEMS LiDAR research and development at the Army Research Laboratory (ARL) to design and deliver a high-resolution LiDAR system - the RTL-450 – to government and commercial customers. 4D licensed the LiDAR technology from ARL, and in a two-year period, transitioned the ARL technology from a benchtop prototype to a commercialized product.

The MEMS mirror-based LiDAR technology provides unsurpassed performance for a wide range of end user applications.High point density and superior target resolution allow advanced Artificial Intelligence and Machine Learning (AI/ML) algorithms development and integration that will drive the future of autonomous systems operations.

The first platform integration of the RTL-450 LiDAR system was onto a UAV to allow 3D mapping of the ground and objects on the surface of the earth.4D’s license with ARL covers all manned and unmanned vehicle applications as well as surveillance.4D is actively expanding its LiDAR product offerings, including the development of a subsea LiDAR system for unmanned undersea vehicles (UUVs) and remotely operated vehicles (ROVs), and the development of a long-range high-resolution 3D imaging system for unmanned ground vehicles.

The MEMS mirror-based LiDAR products can be found at the RedTail LiDAR website. RedTail LiDAR is a 4D company division.
