(54) Title: SYSTEM FOR FREE-SPACE OPTICAL COMMUNICATION AND LIDAR (A) TX, RX, Processor 4 1 / Detector Array Reciever/RX 10 \ 2 Z.. Lens 0 126 5 116 coC 122 Comms/LIDAR System kr) GC N N 1-1 00 O 1-1 N C (57) : A system and method are provided that sit at the intersection of high bandwidth mobile communications and light detection and ranging (LIDAR). The system and method expand on a diverged-beam free space optical system (DBFSO) and solves the LIDAR cost problem by describing a combined LIDAR / DBFSO system. One integrated hardware system provides the capability of both LIDAR and DBFSO, and in many configurations, both capabilities can operate at the same time, while reducing cost and complexity associated with two separate systems. The system can be stationary or mobile, and apply to both scanning and fixed configurations.
