Abstract
  • We present a theoretical free-space optical (FSO) transmitter that utilizes a dynamically steered and shaped laser beam to communicate with a randomly moving receiver adorned with a retroreflector. The transmitter tracks the receiver's position by repeatedly scanning the field of view (FOV), measuring reflections from the retroreflector, and estimating the receiver's position with a Kalman filter. The transmitter sends data to the receiver in between scans. A Monte Carlo simulation is used to determine the optimal FOV subsection to scan at each time step so that time spent scanning is minimized without compromising link reliability. The feasibility of the communication system is evaluated with a hypothetical implementation based on real hardware.
